Collisions and performance

[Vincent22]

Solved!
I've implemented ray casting (using bresenham algorithm to "draw" my ray) to check collisions and now it works

Thank you all for your answers!

Sorry, but I don't understand your suggestion. Can you explain your methods with more details?
thank you

The simple brute force way to do collision detection in a light cycle game is to have a large 2D grid of your world which you set the X,Y points of where there are walls/trails/anything you can hit. If you only need to know "Collision or not" then you can use 1 bit.

It might be the size of your world means the grid is too big (10k by 10k using 1bit is over a gig), but maybe you don't need a 1-to-1 resolution i.e. if the grid 5k by 5k, would the player notice? If the minimum speed is 2 then definitely not.

Hopefully that makes more sense.
