Custom prefabed spawner
Im using this script to generate my floor created with cubes, currently with primitives, but I would like it to use a custom prefab as the cube? How:
for (var y = -9; y < 10; ++y)
for (var x = -9; x < 10 ++x)
for (var z = -4; z < 5; ++z) {
var cube : GameObject = GameObject.CreatePrimitive(PrimitiveType.Cube);
cube.transform.position = transform.position + Vector3(x, 0, y);
}
Best Answer
At the top of your file put:
var prefab : GameObject;
Change your code:
for (var y = -9; y < 10; ++y)
for (var x = -9; x < 10 ++x)
for (var z = -4; z < 5; ++z) {
var go = Instantiate(prefab, transform.position + Vector3(x, 0, y), Quaternion.identity);
}
Select the object this script is attached to in the hierarchy. Then in the inspector, drag and drop the prefab onto the prefab variable.
Instead of calling the CreatePrimitive method, you can replace it by calling Instaniate. Here's an example:
// JavaScript
// Instantiates a prefab in a grid
var prefab : GameObject;
var gridX = 5;
var gridY = 5;
var spacing = 2.0;
function Start () {
for (var y = 0; y < gridY; y++) {
for (var x=0;x<gridX;x++) {
var pos = Vector3 (x, 0, y) * spacing;
Instantiate(prefab, pos, Quaternion.identity);
}
}
}
You can see this in more detail (along with other ways to progamatically create objects) at the official unity API: http://docs.unity3d.com/Documentation/Manual/InstantiatingPrefabs.html
