I'm messing around with a script for the game and I'm trying to rotate a house.
House consists of multiple objects.
I need to rotate a house for certain degrees but I'm not very good at math and need help with the equation.
Let's say I have a Z axis, an angle alpha and I need to rotate house objects around axis Z for angle alpha degrees and keep the house in the same shape.
Let the point on 3D house be $(x,y,z)$. $z$ coordinate is unaltered.
$$ x_1= x \cos \theta- y \sin \theta;\, y_1= x \sin \theta + y \cos \theta , \, z_1=z; \,$$
