Having Problem With Performing Collison with two prefab object.

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.
