Place GameObject on terrain even if player is looking up
Hi I am trying to place a GameObject infront of the player and on the ground "terrain".
I have this code in my Update():
if (Input.GetMouseButtonDown(1)) { // Högerknappen på musen
Vector3 playerPosition = transform.position;
Vector3 playerDirection = transform.forward;
Quaternion playerRotation = transform.rotation;
float spawnDistance = 1.0f;
Vector3 spawnPos = playerPosition + playerDirection * spawnDistance;
GameObject insObj;
insObj = Instantiate(waterExtractor, spawnPos,Quaternion.identity) as GameObject;
RaycastHit hit;
Vector3 ray = insObj.transform.TransformDirection(Vector3.down);
Physics.Raycast(insObj.transform.position, ray,out hit);
insObj.transform.rotation = Quaternion.FromToRotation(Vector3.up, hit.normal);
insObj.transform.localPosition = new Vector3(insObj.transform.localPosition.x, ((insObj.transform.localPosition.y - hit.distance)), insObj.transform.localPosition.z);
}
This works great as long as I dont look upwards. Then the object is placed up in the air. What am I doing wrong here? Please check the small clip on youtube for demostration of my problem : Placement problem
Looking over your code, this is what I think is happening. Unless you have some kind of collider in your sky, your raycast should not be returning a hit. So, you have instantiated an object and later try to modify it's position with an empty value, so it sits there. I would recommend starting with the raycast, and checking if there is a hit, like:
if (Physics.Raycast(ray, out hit))
and then doing an instantiate with the hit.point as the position.
Instantiate(waterExtractor, hit.point,Quaternion.identity) as GameObject;
I hope this helps.
@Justinger : I have now changed my code and it works now :) My code now is:
if (Input.GetMouseButtonDown(1)) { // Högerknappen på musen
Vector3 playerPosition = transform.position;
Vector3 playerDirection = transform.forward;
Quaternion playerRotation = transform.rotation;
float spawnDistance = 1.0f;
Vector3 spawnPos = playerPosition + playerDirection * spawnDistance;
Vector3 fwd = transform.TransformDirection(Vector3.forward);
RaycastHit hit;
if (Physics.Raycast(transform.position, fwd, out hit, 5.0f)) {
if (hit.transform.GetComponent<Collider>().name == "Terrain") {
GameObject insObj;
insObj = Instantiate(waterExtractor, spawnPos, Quaternion.identity) as GameObject;
insObj.transform.rotation = Quaternion.FromToRotation(Vector3.up, hit.normal);
RaycastHit hit2;
if (Physics.Raycast(insObj.transform.position, Vector3.down, out hit2)) {
insObj.transform.localPosition = new Vector3(insObj.transform.localPosition.x, ((insObj.transform.localPosition.y - hit2.distance)), insObj.transform.localPosition.z);
}
}
}
I dont know if it was how you was thinking. Now I will just clean up the code and check so the player cant put another object up on the first one :) Thanks for the help
