Title: Drag Constrain/clamp[SOLVED]
Post by: TerraImagina on February 06, 2020, 06:03:17 AM

Hello,

I want to be able to drag an object to a constraint area only.

I have been following this awesome tutorial about touch control with playmaker,

There is an example that allow to drag an object with touch.
I have been trying to modificate it to constrain or clamp the movement to certain area, but without success...
This exemple use a translate action to move the object, with variable touchXdelta and touchYdelta that come from GetTouchInfo action.
I tried using a float clamp on those variable to constrain them, before the translate action, but the result is not working as intended.
Does it work to use float clamp for a translate action ? Is there another way to constrain a drag object?

Thank you!

Hi,

 this gives a good demonstration of how it can be done:

have you checked the "Move towards with constraint" sample on the ecosystem?

Hi JeanFabre

The "Move towards with constraint" sample was exactly what I was looking. Now I understand the logic of how the constrain is working.

Thank you!
