Issues with 3d camera rotation for a vehicle

lucascodebreak

I trying to make a smooth camera for this car, i tryed a lot of tutorials but dont worked for me.

These is the nodes on the car scene:

CameraBase is another scene because of this:

i used set_as_top_level to detach the child from parent, and this code for place the camera root in the car position:

but when the camera rotate ~180° to 360° from left to right (or right to left) the camera do a reverse loop and go to the correct value.

these are the CameraBase nodes: The CameraBase root node are the X axis, and the "axis" node are the Y axis. and Z axis of the camera is aways 0.

The camera works perfect, but this 360 reverse loop is getting harder to fix (or im just dumb :v )

thank you very much to those who can help me.

Wouldn't it be easier to just use InterpolatedCamera node, and let it follow a spatial node parented to the car?

I don't see your actual rotation code, but it looks like you are using rotation_degrees, which is the problem. Rotation would be similar (in Radians) as they both use Euler angles. The problem is that Euler angles are only 360 degrees (either 0 to 360 or -180 to 180) so you have a disconnect when it loops around. For example, if you are interpolating around the loop, say from 30 degrees to 330 degrees. You only want to move 60 degrees, but the function will instead move 300 degrees (in the opposite direction). There are ways to check for this in code and adjust, but they can be pretty hacky. It is better to use Transforms or Quaternions, which don't have this issue. For example, if you use the rotate_x/y/z functions, they should adjust for this already.
