Well I was creating a TRON style game, but had an issue with creating the actual light trails for the game. What I'm doing currently is I have an array the same size as my window in pixel size, implemented like this:
Then when the bike goes on a certain pixel, it is marked with a
1 for traveled on. However what is the most efficient way to create a working light trail display?
I tried to do something like this:
int i, j; for(i=0; i<800; i++) for(j=0; j<600; j++) if(*collision[i][j] == 1) Image::applySurface(i, j, trailSurface, gameScreen);
But it isn't working properly? It just fills the whole screen with a sprite instead. Whats a better/faster/working way to do this?
