Block Placement Help
How do I modify this script so that instead of creating a standard cube, it instead creates a prefab, which can be specified from within the inspector? For example, instead of creating a cube when the button is clicked, it creates a building, or a tree, or a sherbet lemon.
var distance = 5;
function OnGUI ()
{
if (GUI.Button(Rect(25,25,100,30), "Place Block"))
{
var newCube = GameObject.CreatePrimitive(PrimitiveType.Cube);
newCube.transform.position = transform.position + transform.forward * distance;
newCube.transform.rotation = transform.rotation;
}
}
Try adding a variable at the top "var prefab : Transform" and replacing the whole newCube section with something like:
var newPrefab=Instantiate(prefab,transform.position+transform.forward*distance,transform.rotation);
That will set position and rotation of the prefab at the same time, also.
Thanks, it works. Although, I'm having a problem with my prefab spawning in the air, and although it has a rigidbody, it either hovers in the air or falls through the terrain, depending on whether I lock the y position or not.
That's wierd, but sounds more like a problem with your prefab. Does it have a collider attached and if it does, have you made sure that the "isTrigger" box is not selected? Also, if your prefab is using a mesh collider, that will not work with rigidbodies unless "convex" is selected.
Ok, thanks for the info. How would you add a downward transform to the newPrefab? Because if I could do that, then I could set it up so that it always is placed on the ground? $$anonymous$$aybe get the height of the spawned object above the ground, and transform it downwards that much?
If you put a script on the prefab with something like this:
function Start () {
var hit : RaycastHit;
if(Physics.Raycast(transform.position,Vector3.up*-1,hit){
var hitDistance=Vector3.Distance(transform.position,hit.point);
transform.translate(0,-hitDistance,0);
}
}
it would raycast directly downward, and, if there was an object underneath, move it down to the point where the raycast intersects with the object underneath.
