Detecting a Collision between specific two objects?

Questions & Answers
1

I would like to detect a collision between my character and two specific other objects. The objects are basically triggers to detect if my characters is in a specific location and return a bool value. I’m think some way with the OnTriggerEnter() class, but I do not know how to check whether object entering is the player or not and the objects are in motion. the link below is to a test version of the scene I’m working on and the red meshes rotating are what I’d like to detect collision with.

when using:

OnTriggerEnter(Collider col)
{}

this is attached object A (any object, who cares) then object B enters in collision with A. The script is on A but col is a reference to B of type Collider. So for instance if you want to check the name of the other object:

OnTriggerEnter(Collider col)
{
    if(col.collider.name == "ObjectB")
    {
        // It is object B
    }
}

if you want to recognize a group of object based on tag:

OnTriggerEnter(Collider col)
{
    if(col.collider.tag == "TagB")
    {
        // It is object tagged with TagB
    }
}

When you use OnTriggerEnter() or OnCollisionEnter() the parameters should be (Collision tempParamName)

Then your object should have a “tag” or “name” you can compare the collision with for example:

OnTriggerEnter(Collision sphere)
    {
    if(sphere.tag == "redMesh")
    debug.log("collided with redMesh");
    }
