raycasting issue
I have this weird issue where i Raycast from the red square 2 lines with Debug.DrawLine to verify directions. The lines are correct but both casts returns the values of B square for some unknown reason.
here is my code:
if (Physics.Raycast (Vector3(VerifyBlock.transform.position.x,VerifyBlock.transform.position.y,VerifyBlock.transform.position.z), Vector3(VerifyBlock.transform.position.x+100,VerifyBlock.transform.position.y,VerifyBlock.transform.position.z), hitRight, 7))
{
Debug.DrawLine (Vector3(VerifyBlock.transform.position.x,VerifyBlock.transform.position.y,VerifyBlock.transform.position.z), Vector3(VerifyBlock.transform.position.x+100,VerifyBlock.transform.position.y,VerifyBlock.transform.position.z), Color.cyan);
nameRight = hitRight.rigidbody.name;
textureRight = hitRight.rigidbody.renderer.material.GetTexture("_MainTex");
gameobjectRight = GameObject.Find(nameRight);
if (VerifyBlock.rigidbody.name == "box_1")
{
print("right texture: " + textureRight + " and right name: " + hitRight.rigidbody.name);
}
}
if (Physics.Raycast (Vector3(VerifyBlock.transform.position.x,VerifyBlock.transform.position.y,VerifyBlock.transform.position.z), Vector3(VerifyBlock.transform.position.x,VerifyBlock.transform.position.y-100,VerifyBlock.transform.position.z), hitDown, 7))
{
Debug.DrawLine (Vector3(VerifyBlock.transform.position.x,VerifyBlock.transform.position.y,VerifyBlock.transform.position.z), Vector3(VerifyBlock.transform.position.x,VerifyBlock.transform.position.y-100,VerifyBlock.transform.position.z), Color.blue);
nameDown = hitDown.rigidbody.name;
textureDown = hitDown.rigidbody.renderer.material.GetTexture("_MainTex");
gameobjectDown = GameObject.Find(nameDown);
if (VerifyBlock.rigidbody.name == "box_1")
{
print("down texture: " + textureDown + " and down name: " + hitDown.rigidbody.name);
}
}
Thanks a lot for the help.
Raycast() cast a Ray. That is a position and a direction. It appears you are using two positions. You can change to using Physics.Linecast(), or you can change your Raycasts to use a direction. Note you are going to a lot of unneeded work with your positions. Your right cast would be:
if (Physics.Raycast (VerifyBlock.transform.position, Vector3.right, hitRight, 7))
And then for the Debug:
Debug.DrawRay(VerifyBlock.transform.position, Vector3.right * 7);
Note your calculations as well as my code here is using the World right. If the red cube will be rotating and if you want the cube's right, use transform.right.
wow your right way too much work. Just starting up on Uscript and game program$$anonymous$$g. Thanks a lot that worked very perfectly.
