How I can see that ray from Debug.DrawRay ?
Hi, I just stopped at the OnCollisionEnter event and found an example like this:
void OnCollisionEnter(Collision hit){
foreach (ContactPoint contact in hit.contacts) {
Debug.DrawRay(contact.point, contact.normal, Color.red);
}
}
I tried but...how I can see that red ray ?
Thanks
Update: according to advise from SGamerXxX I modified the code and get the result I want thanks alot:
Debug.DrawRay(contact.point, contact.normal, Color.red, 20, true);
Not sure if this would work, but try turning on gizmos ( Game Window ( $$anonymous$$aximize on Play,Stats,Gizmos))
I THIN$$anonymous$$ you need to call it within update()
the ray is being drawn and disappearing so fast you never see it.
You don't need Update if you add a duration. Turning on gizmos does indeed allow it to be seen in the game view.
@SGamerXxX yes that did it !! many thanks my friend. posted as an answer to check it plz
Thanks for all other replay and help
Good it worked, here is it an answer form as you requested:
Try turning on gizmos ( Game Window ( Maximize on Play,Stats,Gizmos))
You must use both... turn gizmos on AND put the third/fourth parameters as well.... gl
Well, let me ask you this: Are you looking in scene view? Because that's the only place where it's visible. If you are and you STILL can't see it, first add Debug.Log("Collision"); to make sure the collision is ACTUALLY going off, secondly add a duration to the ray so that it doesn't disappear so fast:
Debug.DrawRay(contact.point, contact.normal, Color.red, 5.0f);
If you still can't see it and the Gizmos thing doesn't work out. . . I might have to come over to your house ;)
I've been looking all over for this answer and clicking on scene view was it! I'd +1 you but I cant because I only have 1 rep. haha aww :(
$$anonymous$$ake sure that you are actually Raycasting first and then running your debug piece of code: Debug.DrawRay(contact.point, contact.normal, Color.red, 5.0f);
In my case, I was declaring the Ray and just after was trying to run this Debugging before my raycasting actually happened.
Obviously but still...
So the ultimate recipe is: - Run Debug.DrawRay after raycasting is happened - Turn on Gizmo - Add DrawRay duration
Result: Ray visible as in Scene, as in Game view
