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!
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.

QuaziGNRLnose: Thank you for your advice!
Could you point me to recommend a book to study material or mathematical concepts as necessary to be a great developer?

I like math!

Try Googling for "mathematics game developer"

Or try here

But remember why we actually have behaviours in C2..

However if you get to be an expert, be sure to write some behaviours/plugins
