transform.Rotate is returning unexpected results
Hello, I have a question. I probably missing some basic knowledge, because I do not understand following scenario:
I have an object, whose rotation is [0,0,0]. Then I run following 2 commands:
transform.Rotate(45, 45, 0);
transform.Rotate(-40, -40, 0);
Result is rotation = [-2.268; 15.476; -27.057] I would expect something like: [5;5;0] Thanks
If you take a closer look at the documentation, you will read the following:
Transform.Rotate
Description
Applies a rotation of eulerAngles.z degrees around the z axis, eulerAngles.x degrees around the x axis, and eulerAngles.y degrees around the y axis (in that order).
If relativeTo is not specified or set to Space.Self the rotation is applied around the transform's local axes.
So, the applied rotations are:
+45° local X axis
+45° local Y axis
-40° local X axis
-40° local Y axis
The result can't be (5°, 5°, 0) because the rotation are applied to the local axis in the order XYXY. However, if the rotation would have been applied in the XYYX order, you would have a final rotation of (5°, 5°, 0°)
@Hellium thanks for your answer. It makes sense to me if I simulate it step by step. It's very difficult to calculate and imagine from top of my head though. Especially mixing both world and local coordinates. Is there any hint? Thanks
I don't have any tips unfortunately, and I think you have no choice but calling transform.Rotate multiple times to have the "step by step" process if you want to get back on your feets.
