Having Problem With Performing Collison with two prefab object.

[anon93345271]

Hi,... I'm new to unity .This is my first 2D game project.

I'm using two prefab object 1) DropObject 2) HitObject

1)DropObject:

• Added BoxCollider with - IsTrigger -Yes -Size X=5 y=5 Z=10

• Added Rigidbody with default and - UseGravity -No - Is Kinematic -No

• It is not a moving Object

• This Object is instantiated to 36 Objects

2)HitObject:

• Added BoxCollider with

  • IsTrigger-Yes -Size X=3 Y=2 Z=10

• Added Rigidbody with default and - UseGravity -No - Is Kinematic -Yes

• It is a moving object.

• This Object is Instantiated to 4 Objects.
• It is the Object that hit the DropObject.

Both the DropObject and HitObject have the Z value as 0.

• I have Used Collision Detection functions like OnTriggerEnter() ,OnCollisionEnter(),OnCharacterCollision().But they are not executing (Checked with print() ).

What do I do to Detect Collision between these Objects.

You need to attach a rigidboy to one of the cubes. OnCollisionEnter and OnTriggerEnter only fires if one of the colliders is a rigidboy.

You can turn off the gravity in the rigidbody if it is interfering with your logic.
