TOPIC: Rotation Problem

Rotation Problem 1 year 1 month ago #3112

I've been working on a new movement system for both third person and first person and I keep running into this problem where if the player (in this case a cylinder) rotates beyond 90 degrees it starts rotating fast like crazy.

I'm not sure if this is a bug but I need some help fixing.

Here in the video you can see in the top left, when the rotation goes beyond 90 it'll start glitching out:

Greetings,

When it comes to applying rotation to a collision object, it can pose some difficulties.
Therefore, we recommend using the "Rotate Towards" command instead.

To illustrate this, please refer to the following example:

Thank you so much it works perfectly!

Here's how it looks now with added movement:


Still needs work before releasing but I'm happy with how it is.

It's great to hear that your game featuring a dynamic third-person controller is progressing well.
We are confident that it will turn out fantastic with the additional improvements you're implementing.
Keep up the excellent work!
