Title: How do you move toward a vector position using force? [SOLVED]
Post by: Gav (HeyBud) on September 16, 2018, 07:54:56 PM

If I want to move a physics2d game object to a desired x and y how do I know how much x and y to apply force to move in the direction of the object? Is there an easy way to do this? ??? Similar to Move To action but physics based.

Maybe with iTween Move To with Setting time ?

That would be great, but I think I tween move uses translate and not physics force. Am I wrong about that? The problem I'm having is when you translate, collisions are overridden or something. Only using force can you get good physics collisions.

I am beginner to Playmaker.
I don't get what you saying.

I faced a similar issue while started to learn. Found solution here

Yeah, that makes sense. So I guess my question is a math question. how do I calculate the vector i need to plug into 'set velocity' to move in the direction of another position? I want an object to move to another object using physics.  This would be a super useful custom action!



I'm not good at maths.

Hi,

 to get a direction, you substract the target position with your current position, that's your direction.

 you then use that as the base vector to apply your force.

This works thanks. It felt like I was over-complicating the question so i'm glad there's a simple solution.
