Invisable Projectile; Instantiate at Collisions
Hi, is there any way that I can instantiate something only at game objects that have a collider attached to it? I don't want to see the prefab travel, just instantiate at a collider (a wall).
For example, if the player is facing toward a wall that is far away and I click the fire key (Input.GetAxis("Fire")) the prefab would instantiate at the collision (the wall)?
public class InstPrefabs : MonoBehaviour {
private void InstThePreFab() {
Vector3 fwd = transform.TransformDirection(Vector3.forward);
if (Physics.Raycast(transform.position, fwd, Mathf.Infinity)) {
Instantiate(prefab, transform.position, Quaternion.Identity);
}
}
}
This is kinda funky.
What I have, is when anything (both raycasts and projectiles) collide with something then it plays the collision sound (which is the sound attached to the prefab in the audiosource).
Raycast, and instantiate what you like at RaycastHit.point.
can OnCollisionEnter be invoked when this raycast collides with a collider?
No. I could see how you might think so, because a wheel collider utilizes raycasting, and it works for that, but no.
No, but you'll get the same sort of behaviour if you read my answer in the link I posted.
Check out this similar question. It contain full code in C# to make a RayCollider. With minor modifications you can ask it to test ray when pressing button. You can then have code such as
void OnRayCollision(RayCollision collision)
{
// spawn prefab at collision.hit.point
}
Did you even bother to follow the link or read what I wrote?
That's what you get for giving the men fish after I taught them how to make a rod and raise worms! :-D
Well, I see no big difference. Unity contain code. $$anonymous$$y answer contain code. If unity provide a method to check for collisions and I provide a method to check for collisions, what does it matter? Productivity should matter. But hey, it's nice to see you're describing yourself a $$anonymous$$cher and me a fish dealer.
I don't think you understood what I said. What I'm saying, is that you keep giving more elaborate answers than I do (and in one case edited my answer to be so), and while I think your answers have looked more informative, that doesn't mean the asker is going to appreciate them more. $$anonymous$$y approach is to provide the smallest amount of direction I think would have helped me understand the solution to the question. I hardly know most askers here, so I can't really tailor the results to them, and there are other things I need to do with my time.
