How do you detect if two specific objects are touching each other without collision.
My game's bird's eye view and i want to have a certain game object that gives input when the player's on top of it
you can implement your own collision detection system or use rycast for this.
Why not use collision?
You -could- shoot a raycast down and check to see what you're hitting. This is more expensive, though.
If it's birds'-eye, just put a check in your update to see whether the player's 2D coordinates match that of your game object.
Update()
if (transform.position.x == player.transform.position.x &&
transform.position.z == player.transform.position.z)
{
//Do some thing
}
Something like that would work.
This wouldn't work very well that's just checking if it's at point, it could be 0.001 off on one axis and this wouldn't work...
If you don't want to use collision you could perform a distance check.
if (Vector3.Distance(player.position, other.position) <= 0.1f)
DoTheThing();
I dunno why people wouldn't just set it to isTrigger sounds like what OP wants.
because it feels like he is asking of a solution for checking collisions without unity physics, and the easiest approach for that would be rycast
I think he wants to check if his player is on top of a position, he just doesn't want it to have collision. Anyway this answer is probably the thing to do.
