I'm wondering if anyone knows how the range units used by trgtrangecondjump scale to the units used by weapons.dat. It looks like around 32 units per 1 weapons.dat unit but I'm not too sure.

trgtrangecondjmp uses pixels as its units, so it would be 32. You are correct.

1 weapon range = 16 pixels.

Oh thanks. That explains why the ranges are all off
