@Jack8680 Thanks. I solved the problem by using the "Multiply Values" to times the index value and degree value in the loop. As following pic.
Thanks a lot.

Thank u.
I tried the rotate by behavior, as attached pic. However it's the same, only rotate once but not repeat 5 times in the loop.... anywhere wrong?

I'd like to rotate an object 5 times in a loop. I setup it as the attached pic, but just rotate once.... anywhere wrong?

@Murtaza Yes, I redo it again, and everything is fine now. tks.

@Jack8680 please check http://bit.ly/2wBhpnq , level 1-1, the blue button.

It might be the problem that I imported the project from GamePress then add some new features on it. If I do it totally new on HyperPad, it works well.

I'll try to redo it again on HyperPad, tks a lot.

@Jack8680 Surely I selected the right object, and set the "constrain area" for the drag-n-drop behavior. I got x, y numbers of the area, but just cannot move the object correctly as the setting.... :(

It's the same problem. I set the area, but can not drag and drop in the area correctly....

When I set the area for "drag-n-drop" of an object, it always moves incorrectly.

Is that a bug ?

Thx.
