Hi conitec,

I'm very sure, that the vector mouse_dir3d doesn't return correct values for the mouse to level direction anymore. I'm using this vector in a lot of functions (placing entities with the mouse using c_trace, placing decals using c_trace, calculating target vectors for the point the mouse is pointing at etc. etc.) and all of these functions return completly wrong results since I updated from A7.60 to A7.70.

I can not confirm any such problem.

I think I got the problem now.

Could it be possible that mouse_dir3d was previously normalised to a length of 1 or at least to a very low value and now it's not any more?

I previously used vec_scale to scale the direction to the length I wanted it to have - assuming that a direction vector is already normalized to the length of 1. When I now use vec_normalize instead, it works fine.

You're right, it's not normalized, but it wasn't normalized before either. The engine uses a vector of length 1 in screen coordinates and backprojects it to world coordinates. So it's final length depends on the screen size.

I'll normalize it from the next version on.
