It's just an annoying bug.
I was using arctan: one block facing the other
The block that used arctan (which was facing the other one) has a text set to its position, repeated forever.
Arctan doesn't work from this
By the way, does anyone know how to use arctan so that the object facing another doesn't angle to it, the only angle reference is when it moves forward, it moves in the direction of the object it is "facing"?
