Collisions Not Working On Non-Physics Objects

Recommended Posts

Hello again,


Once more, I'm having some issues with the collision system. I have an object in my game that I want to have bouncing back and forth between the map walls that will act as an obstacle for the player character. I cannot use a physics object for this, as it makes the object's behavior inconsistent and difficult to control after its first collision. However, with its Mass set to 0, it no longer registers collisions with the map walls. It will collide with a player character (which is a physics object) and react as it is supposed to, just not with the walls or any other non-physics object placed in the scene.


What can I do to correct this and have it register collisions with non-physics objects?






I don't think it is helpful, but I have included the object's settings and script below, just in case.


Physics Mode: Rigid Body

Collision Type: Character (I have tried every available type and none of them solve this issue.)

Mass: 0

Character Angle: 0

Swept Collision: False

Nav Obstacle: False


Script.moveSpeed = 5.0 --float "Movement Speed"
Script.initDir = -90 --float "Initial Direction"

function Script:Start()

   self.entity:SetRotation(0, self.initDir, 0, true)
   dirFlip = 1


function Script:UpdateWorld()

   self.entity:Move(0, 0, self.moveSpeed * dirFlip, false)


function Script:Collision(entity, position, normal, speed)

   dirFlip = dirFlip * -1

in your start function and set your mass to 10. This will make your object collide with the walls.


Unfortunately the ball starts going all over the place after hitting the walls twice. Don't know whats going on I'll check again tomorrow once I've had some sleep.

Moving objects with SetPosition or Move will break Physics simulation. What if you give it a mass, set collision to Trigger so it doesn't bounce itself and then control it's movement with PhysicsSetPosition?
