A bot that plays the Google Chrome T-Rex game for you. It can consistantly hit around 50,000 points. Highest I've gotten is 100,000 but I'm sure it can go much higher.
When I had started this project I thought this would be at least 200 lines of code, and yet here I am hitting 6 figure scores where the bot itself is just 10 lines of code. Now obviously I have to simulate the key inputs, and that's what takes up the other 50 lines.
I've been able to make it so short by finding a formula to calculate how far away I need to jump before an obsticle. I found this by just straight up playing the game and logging the exact speed of the T-rex and the distance away from the obsticle at the time of jumping. I had then put them into graphing software where I found the correlation between the speed and distance. Distance = Speed * 25. Always.
