alert(` Compatible for all devices. Kindly upvote this code, it takes a lot of efforts to make AI codes (eg: Car, 2048 both are almost perfect). You can make your own road by changing the co-ordinates of the road (line 35 in js) to test the AI But make sure that: 1. The points are not too far away (avg 40-50). 2. The points should be very close while taking turns. 3. The road formed should be enough wide for the car to go. 4. Also don't forget to give it a direction: You can do this by changing the value of 'direction' variable to either 1 or 2 (line 40 in js) 5. To test the AI further, you can change the starting position of the car from the html page (not css). You can also set a starting place out of the track, the car will come back to the track itself. 6. You can also change the initial direction the car is facing by changing the value of 'rot' variable (line 40 in js) 7. If you see the car crossing the track then it means that the points given by you are either far away or the road is too narrow for the car. 8. You can also increase or decrease the speed (by changing the value of 'speed' variable in line 40 in js) of the car without worrying about the car leaving the track 9. Tell me if you find some bugs (and also tell the track coordinates you used when the bug can be seen). The red and blue lines show that from where the car is getting information to turn (perpendicular distance and angle of rotation). `) var road = [ // outer boundary [[40, 90], [70, 60], [100, 50], [180, 40], [250, 50], [300, 70], [360, 100], [380, 150], [380, 200], [350, 230], [330, 245], [300, 255], [280, 280], [290, 300], [310, 330], [360, 380], [360, 450], [330, 490], [300, 510], [250, 515], [200, 520], [100, 510], [70, 470], [40, 420], [20, 350], [20, 280], [20, 200]], // inner boundary [[110, 130], [130, 120], [180, 110], [240, 110], [300, 130], [320, 170], [300, 190], [260, 205], [220, 250], [220, 300], [240, 340], [260, 380], [270, 390], [290, 410], [280, 430], [240, 445], [200, 450], [150, 440], [125, 410], [100, 360], [90, 300], [100, 190]] ], body, car, turn=0, speed = 3, rot = 0, t1, t2, direction = 1; const pf = (x) => parseFloat(x); window.onload = function() { body = document.getElementById("CarAI"); car = document.getElementById("car"); for (let points of road) { for (let i = 0; i < points.length; i++) { let next = i < points.length-1 ? i+1 : 0; let x1=points[i][0],y1=points[i][1],x2=points[next][0],y2=points[next][1]; let width = Distance(x1, y1, x2, y2); let angle = Angle(x1, y1, x2, y2); //angle += (y2>=y1 && x2>=x1) ? 0 : 180; //body.innerHTML += [...points[i], ...points[next]] + "
