Title: Collision issue when moving object with "Translate" action [SOLVED]
Post by: app_advisory on June 12, 2014, 06:58:25 AM

Hi,

I don't know why, but when I move my sphere continuously with a translation, the sphere enter a little bit inside a wall when there is a contact between the sphere and a wall..

I attached a little video, and my FSM and the inspector of my sphere.

Thank you very much for your help ...

Regards,

Anthony

Hi.

The first thought that came to my mind is maybe you should try increasing the radius of the Sphere's collider? Or try a cube collider? (Incase you haven't done so) Sorry I'm rather new to Playmaker myself and that's all I can think off.  ;)

I'm new too ;)

What's the consequence of the increase of the radius ?

I saw it change the "collision" surface but .. It didn't change anything

In general you should move a Rigid Body using forces instead of Translate. Translate overrides the physics simulation causing weird behavior.

Or you could use Set Velocity to set the velocity directly.

Or use a Character Controller and Controller Move or Controller Simple Move actions.

There are pros and cons to each approach, so it would depend on the needs of your game...

Oh ok nevermind then. I keep thinking Collision has something to do with the objects physics, but Alex Chouls is right, I think you'd have to do something with the Rigid Body to solve this.

Hi,

You're right : set velocity is better ..

And it solves my issue thanks a lot !!
