LÖVE

I went back to using love2d to play with my new knowledge of opengl, using shaders to make a game in 3d, but there was an error in the part of sending the value of the matrices to the shader, I had already made 3d in love2d a while ago.

The first vector of the proj matrix only has 3 values, not 4 values. It runs once you add an additional 0 into the first line of the matrix vector

Also feel free to delete your two other posts, since they are duplicates.

I don't think you can delete posts unless you are a mod.
