You need to decouple your rendering from your Bresenham iterations. Just make it a separate bresenham function that you'd call as in my example above, and update/draw your game independently. Also, learn about what a game loop is: active.tutsplus.com/tutorials/games/….

Changed suggestion to slow down movement.

If I try to update with each iteration of the Bresenham, the rendering happens too fast. Why wouldn't this happen if I'm just looping through it? Should I call the update function (which increments pathIndex) based on the timer interval? Bresenham is already implemented and too way too long. >< I just have to figure out how to get pathfinding working in time, and I'm very worried about that. | |

And if you're still confused, well, ask another question :) If there's something you'll use lots of times in gameplay programming, it's the lerp function. But for the moment, forget about lerp, you can just advance on your path once in a while, I'll edit my answer above to reflect that. Oh and by the way, maybe Bresenham is overkill for you, you should probably forget about discrete-grid motion and try out what Jimmy suggested: gamedev.stackexchange.com/a/26347/14808. | |
| Apr 4, 2012 at 16:34 | comment | added | user422318 | Thanks, I like your idea of using a cached path and I'm trying to make that work with my code. I think that it will run too fast, but I haven't found any good resources on doing lerp. Are there any that you'd recommend? The best resources would be one that can explain the math to me like I'm 5 years old. :) | |
