Wei Wei gestured and found that the tablet in his hand was actually a little smaller than his open palm, and he looked up and asked, "Is it a little smaller?"

"The screen is 5 inches diagonally long, and the whole is about six inches over. In fact, it is a large screen MP4 color screen, 800 by 480 resolution, which is also a helpless thing, there are only a few screens on the market. The resolution is smaller, the processor pressure is small, and the resolution is too large to move. ”

"Also, it's equivalent to the resolution of five or six mobile phone screens, which is not small. Are there any games that you don't have?"

"Pre-installed "Biology Department to Find Differences". ”

The game is derived from the popular casual game "Let's Find Differences", which is popular with girls, and the rules of the latter are very simple, two similar pictures appear on the screen, and there will be several differences, and players need to find all the differences in the shortest possible time, because the rules are simple and popular, and the development is very easy, and there are many imitations on the Internet.

It's very easy to make a "find the difference" type of game, collect some pleasing pictures: beautiful stars, architectural attractions, cartoon images, pet animals and plants, still life photos, etc., use photoshop and other retouching software to change four or five "different" on the copy, you can use it as a game level, the simple rules of the game make the program code scale is also very small, using event-driven programming tools such as VB can easily make a new game to find the difference, and the same is true for "Biology to Find Differences".

Compared with other "find differences" games, the main highlight of this game is that it is more exquisite, with a certain knowledge, it uses a large number of pictures of animals and plants as levels, and on the basis of maintaining the commonality of "pleasing to the eye", it also adds a certain educational and popular science significance.

The game is divided into traditional mode and innovative mode, and the traditional mode gameplay is the same as that of ordinary "find fault" games, including normal mode and limited-time mode.

The innovative mode requires the player to find the male creature in the two images in the shortest possible time, and the player can also change the game objective to choose the female creature in the settings.

"Once, Jiajia and I had an argument about a husky's male and female, and no one could convince anyone. Then I suddenly had an idea, why not make this 'male and female judge the male and female of animals' into a game? It's both entertaining and informative, and that's how the biology department comes to find faults. ”

"Cut~!" Wei Wei didn't feel at all about Atletico Madrid's boasting, "What kind of innovation model do you have is just turning the four ABCD options of the exam questions into two AB options, and they are all matched with pictures, how can there be any innovation?"

"This is also an innovation, I was the first to combine multiple choice questions with a 'find the difference' game. ”

"The biology department is too bad at the difficulty classification, the first level "Chickenformes", the point of bright feathers is right, it must be male, the second level "Passerine", or the point of bright feathers, and the third level "Gooseformes", continue to point to the beautiful feathers. This game is that there are too many birds, and there should be more orangutans, monkeys, wolves, dogs, cats and tigers, cows, sheep, horses, donkeys, insects, spiders, etc. ”

"In that case, it's too difficult, can you tell the difference between a female mosquito and a male mosquito?"

"No, you can't. Wei Wei was also simply, "I only know that male mosquitoes suck plant juice and don't suck blood, so there are more near plants and trees." That's right, for the more difficult ones, you can work on the background picture, and add some clues such as the living environment, action posture, etc. to reduce the difficulty!

"It's done. ”

"That's right, I have another idea that comes to me, and I can't stop it!" Wei Wei said excitedly: "If you only distinguish between male and female, for familiar animals, everyone knows that the big rooster has a cockscomb and gorgeous feathers, and the male and female of the duck and white goose may not be known to many people, at least I don't know." So I think we can look at a simpler way to play, instead of judging the male and female, judge which one is real and which one is fake!"

Breathing a sigh of relief, Wei Wei said: "Like the pictures of thumb cats and teacup dogs circulating on the Internet, many people don't know whether they are true or false. Pictures like this can be used as a title level, and pictures of animals and plants that look really strange and don't look like earth creatures can also be used as a level. In order to reduce the difficulty and at the same time facilitate the inheritance of the program framework of "College Students Come to Find Differences", it is also to display two pictures at a time, with at least 50% correctness. Then this gameplay mode is more convenient to promote to other gameplay. ”

"That's a good idea, but the animal and plant introduction text of "Biology Department Comes to Find Differences" is at the beginning of the level, and since this is a guess of whether it is true or false, you should wait a few seconds after the end of the level. It turns out to show the basis for judging the truth and falsehood, so as to achieve the maximum effect. ”

"So the bee company accepted my suggestion, is there a reward?"

"Gift cards for bee universal gold coins should be taken to students, and one can be exchanged for 100 gift gold coins. ”

"That's all?" Wei Wei was a little disappointed, and his tone couldn't help but be a little lower, "The gold coins of the giveaways are all bound, and they can only be consumed but not cashed, so it's useless!"

"Of course, that's not all," said Atletico, "and you can also create your own spin-off game of Biology to Find Fault in the Bee Intelligence Center." Whether it is paid or free advertising, it is up to you, and the bee company shares with you. ”

"How's the money?"

Atletico Madrid: "There are not many paying players in the smart center now, and the advertising revenue is average, and it is still in the development period......"

"Forget it, forget it!" Wei Wei suddenly became excited, turned his head and looked at the time of projection under the windshield, it was close to 12 o'clock at noon, Wei Wei asked: "It's 12 o'clock soon, where will I solve lunch today?"

"There are no good restaurants here, if you want to take your sister to experience our hard desert island life, I can take you to experience life. If you don't want to, go to the market and buy groceries, and then go to my house to cook. ”

"Then go grocery shopping, to be honest, I really didn't expect you to be so good at cooking, and you really don't miss those restaurant chefs." Jiajia doesn't usually need to go into the kitchen?"

"Come in, she usually does it all the time, and girls are more careful about it. ”

"Okay, okay, housewife, cook and classmate Atletico Madrid, show the way!" Wei Wei put the electronic notebook in his arms, sat down and pressed the power button on the steering wheel, and restarted the car, "You have a good modification, you don't need to clutch or gear or something, driving a real car has become a racing car game is still simple, I'm afraid that you won't be able to drive this car if you are used to it." ”

Atletico Madrid clicked a few times on the center console, and Wei Wei saw a string of slowly flashing green vegetable icons appear on the windshield, "That's the route to the vegetable market? ”

"I spent hundreds of thousands of dollars to modify the electronic system, certainly not to get a car computer to watch movies and play games, the real focus is actually this HUD head-up display system, as well as the head," Atletico Madrid pointed to the roof of the car, "The lidar system is the real money." Laser pointers are easy to buy for a few buckles, but the motors in the turntable below them are much more expensive. All of them are imported, and they are used on high-end industrial robots, which are small in size and high in precision. ”

"Radar made with laser pointers?

"The traffic is too small, in order to save power and save life by default. After all, it is a civilian product, although it is a few streets away from most military products in terms of advanced technology, but it is pitted in terms of durability and stability, and it is necessary to save some use. ”

"Isn't radar microwave?Lasers can also be used as radar?" Wei Wei didn't forget to ask while driving along the instructions of the green vegetable icon on the screen to the vegetable market.

"Okay, I've already recorded your words, I'll send it to Teacher Fang when I get back, and see how he cleans you up then." It's a pity that I can't see it with my own eyes, it's a pity!"

Light is also an electromagnetic wave, and a laser is also an electromagnetic wave. Wei Wei hurriedly explained.

"There are advantages and disadvantages of laser radar, the advantage is that the wavelength is small, the detection accuracy is high, and the disadvantage is that the directivity is too good, and it is not easy to capture the target. Moreover, the water vapor, rain, snow, haze, sand dust, thick smoke and so on in the atmosphere will cause the detection range to shrink. ”

"And then you have to wait a minute, and you have to say that this is the civilian version, which doesn't need too far a detection distance, but what you need is the advantage that the laser pointer can be driven by a few batteries, right?"

"That's right, add 10 points, no reward. In fact, the main use of lidar is topographic surveying, with high accuracy, and I actually use ultrasonic radar or sonar on this car. ”

"Isn't sonar used by submarines in the water?"

"Sonar, soundnavigationandranging, sound navigation and ranging, has nothing to do with water, sea, and sea. Bats have been using this system for 50 million years, and the echolocation system of sea pigs has not evolved until 10 million years ago. ”

"What's the situation with the sea pig?"

"It's a dolphin! Dolphin means pig, the Yangtze finless porpoise is also called ****, and the dolphin is called a sea pig. And I found that our ancestors had absolutely no names! Dolphins are really relatives of pigs, although they were relatives 50 million years ago, but distant relatives are also relatives, aren't they? I recently did this "Biology Department to Find Differences" with Jiajia and read a lot of information, and then I learned that genetic analysis proves that the ancestors of cetaceans are the same as the ancestors of pigs, cattle and sheep, and they all belong to the order Artiodactyl. Whales are most closely related to the African hippopotamus among the living animals, and the hippopotamus looks so much like a pig that taxonomically once put the hippopotamus family and the pig family together, called the pig-shaped suborder, so it is no problem for dolphins to be called sea pigs. ”

"Stop, stop, you can call the bogs if you want, I still think the dolphins are better." Wei Wei parked the car at the "P" mark according to the prompts, and said as he got out of the car: "Why is it lidar and ultrasonic sonar, why don't you use radio wave radar? Anyway, the required detection distance is not high, and the power should be able to bring it, right?"

"The belt can definitely be brought up, there are individual radars, and the vehicle-mounted radar must be fine. However, the problem is that our country has a radio administration, but no light wave administration and no sound wave administration. Joke and joke, the real reason is that the electromagnetic wave environment in the city is not good, and radio waves of various frequencies are everywhere, which is not as simple and direct as lidar," said Atletico and slammed the car door shut, "Pay attention to the ground!"

Wei Wei looked down and found that a shadowy red halo appeared on the ground under his feet, on the wall beside him, and on the trunk of the tree beside the road, which disappeared in the blink of an eye.

"This is the LiDAR start-up, which automatically creates a 3D model of the environment, and it can scan the buildings, roads, trees, and other things around the vehicle in two or three seconds to create a 3D terrain model. ”

"What's the use of that? The radar is turned off when you're driving, and it's only here when you're parking?"

After looking around, Atletico waved his hand to signal Wei Wei to come to him, and then whispered: "Lidar can also be used as a self-defense and anti-theft system." Wait a minute, you can hide from a distance and watch this car, and at the end of the year, petty thieves will come out to generate income and have a fat year, and then you will understand what this system does. ”

"That's it?" Wei Wei raised his hand to point to the lidar system installed on the roof rack, but quickly reacted, put down his hand and whispered: "The power of the laser pointer is all milliwatts, it shouldn't be lethal, right?"

Although his mouth was full of suspicion, Wei Wei still chose to wait not far away under curiosity. Anyway, he doesn't have much grocery buying skills, and Atletico doesn't need him as a coolie porter.

A few minutes after Atletico left, Wei Wei found out that there was a situation.

Of course, as an ordinary college student, his eyesight was not enough for him to spot the thief in the stepping stage, and he saw "passers-by who behaved abnormally".

A passer-by suddenly rubbed his left eye with one hand, and after a while he put his hand down, walked a few steps and rubbed his right eye again until he walked away from the car.

Another passer-by suddenly covered one eye with one hand, and then the other eye was also covered, and after a while his hands were lowered, and after a few steps he repeated the action, he crossed the car and turned around and covered his eyes violently, and after a few times, he walked away. Wei Wei noticed that when he turned to look at the car, his eyes seemed to suddenly flash red, and then disappeared.

The passer-by just now wore a pair of sunglasses and passed by the car again, he seemed to be very curious about the Mercedes-Benz parked on the side of the road, and looked at it from time to time, and suddenly he covered his sunglasses with both hands, as if he saw something that should not be seen. Shaking his head, the man walked away from the car.

This time, it was the same passerby who had just passed, wearing a motorcycle helmet and a large wrench in his hand, walking briskly towards the car. Even Wei Wei, who was just an ordinary person, could see that the man had obvious bad intentions and was in a hurry about what to do, so he saw that the man stopped and threw the wrench towards the car, and he himself screamed and bent over and squatted on the ground with his head in his hands, Wei Wei clearly heard the man let out several screams, and then the man turned around and ran away.

He never appeared again after this time.

At this time, Wei Wei also understood what Atletico Madrid's so-called self-defense and anti-theft system was, it should be to use a laser pointer to irradiate suspicious people around it, and give different levels of irradiation intensity according to the different behaviors of the target. Motorcycle helmets can still cause temporary blindness in the eyes, but I don't know if the last time the person screamed and squatted on the ground, I don't know if it was the highest intensity.

"But if someone throws weapons at it, how can this system defend itself?" The large wrench that the man had thrown was still lying on the ground not far from the car, its plating exterior shining silver in the sunlight.

"That's right. Atletico Madrid, who came back from grocery shopping, put a few plastic bags in the trunk and said: "Even tanks are afraid of Molotov cocktails, let alone my civilian car?"

"Civil cars, your car's combat effectiveness will definitely kill all white-plate (military) vehicles, and only those armed jeeps without license plates can fight, but I estimate that they may not be able to do it, laser blinding is too bad. ”

Atletico hurriedly shook his hand, "No blindness, no blindness, too little power will cause dizziness at most, and your vision will be restored after a few minutes of rest." It is not possible unless he is standing within a meter in front of the car, and the air needs to be clean enough. Well, the air cleanliness here on Ludao is among the top in the country, and this system can be used here, so it is not easy to put BJ. ”

After putting the dishes away, Atletico took out a digital SLR camera with a huge flash, clicked and took more than 30 photos at all angles of the big wrench lying on the ground, and then put the camera back in the car, took out a plastic evidence bag and handed it to Wei Wei Wei to put on white gloves, took the plastic bag and picked up the wrench and stuffed it in, and sealed the bag with the anti-counterfeiting tape at the mouth of the bag.

"Hey, hey, hey, is it so professional?" Wei Wei was confused by Atletico's outfit, and waited until he put the wrench away, and then asked out loud.

"It's necessary, it's too necessary!" Atletico suddenly said in a loud voice: "In a legal society, evidence comes first." With the fingerprints on the wrench, the photo just now, and the whole process of the car camera coming and going down before, I can sue the car thief for intentional damage to property. ”

"If there is no loss, there should be no case, right?"

That's why he had to keep the evidence and wait for him to jump out on his own. Believe it or not, the car thief himself or his accomplices are watching from the sidelines, and if he asks me for medical expenses, I will definitely pay for them, and then I will send him to the detention center for eye treatment. ”

Thumbs up his right hand, Wei Wei said that he was powerless to complain, "I don't understand your world!

"What's not to understand about this? Eating a trench and growing wisdom are all learned through practice. Do you open it or do I open it?"

"Go ahead, your car is too smart to feel like driving. Wei Wei shook his head and sat in the passenger seat.

"You know that Jiajia was blackmailed when she was shopping before, right? "What would have happened if she hadn't been wearing camera glasses? So I understand, in a legal society, evidence comes first http://m.piaotian.net!"
