### Search help

• Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
• You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
• cat dog --matches anything with cat,dog or both
• cat +dog --searches for cat +dog where dog is a mandatory term
• cat -dog -- searches for cat excluding any result containing dog
• [cats] —will restrict your search to results with topic named "cats"
• [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

# Simple rotation in blueprints. ( Rotators and range? )

 0 Hi, I'm trying to rotate an object about a point. I have the idea of how in my head but I'm running in to some issues with the actual math involved. Now I don't know too much about vector math, or quaternions, specifically rotations and things like gimble. Now everything is functioning as I want it too except that I have a problem when I hit 90( for example on the Y axis ) on my rotation. When I do that it starts to jitter slightly and it tries to stick at a value of 90. I can modulo that back to 0 so it doesn't freak out. But of course when doing that the object moves back too, essentially, it's start point and the rotation starts over. This only gives me 45 degrees of rotation. So I have two questions. 1: Why is this happening? Is this the gimble lock thing? If I understand why it's occurring then hopefully I can avoid it in future. 2: How can I rotate the full 360 degree's on any given axis? Here's a snapshot of what I'm currently doing: Here's how I'm setting the rotator. I've also tried world rotation and it's the same result.
