Hello there! I want to run a satellite type movement but is a spike ball that has a string attached to the center.

Something like this:

Thank you very much! :)

@Wenaptic - Use image points and the "Rotate clockwise" or "Rotate counter-clockwise" actions. You can also use the "Pin" behavior for the satellite and the "Rotate" behavior for it's center of rotation.

Thanks @CODAH for your quick response!
For now I can not open the CapX and asking me a plugin that I do not find.

@Tetriser your advice works! Thank you very much! :D

PD: I leave the examples to be seen working.

darn, sorry about that. Probably the 'Pin to image point' behaviour... highly recommended BTW..

@CODAH not worry. Your intention to help is invaluable to me. I searched the forum behavior, but found this one. Also with the help of @Tetriser already solved. :)

set position to
x: pin.x+cos(angle)*radius
y: pin.y+sin(angle)*radius

this is such fundamental math, anyone making games should invest time into learning basic trig concepts. You'd be doing yourself a great service. The pin behaviour is just using the same method, wrapped up into the behavior. Learn the math, you'll be able to do complex things without relying on behaviours.
