Thanks for the test case. I haven't looked in enough detail, but when the problem is happening, you are dividing 0/0. When the ray starts at the edge of the box (for example when e.x - ray.ox = 0) and the movement is parallel to the edge (ray.mx = 0), the division returns NaN and the algorithm is n...

I'm trying to make a tile based game, and I've been trying to make this collision system. What it does is it takes the player's velocity, checks for collisions between where it is and where it will be, and adjusts the velocity to prevent collision. It's almost working perfectly, but there's a bug th...

I got this fixed on another website. The problem was 100% lag, because of drawing all those points every frame. What I needed to do was render the data onto a buffer and draw that buffer instead of each individual point every frame. One thing I experienced is that canvases didn't work well, and I'm ...

Hello, I'm trying to generate some terrain to make a game similar to Risk. To generate the terrain, I'm using love.math.noise. for x = 0, 800 do for y = 0, 600 do value[x] = value[x] or {} xCoord = x / 800 - 0.5 yCoord = y / 600 - 0.5 Noise = love.math.noise(xCoord, yCoord) value[x][y] = Noise end e...
