Counting number of blocks in an area
Title sums it up. I have been working on random generation lately. I have made it so when water is generated, there is a chance that a "water checker" is spawned. What I want the water checker to do is count the amount of water in the area to see if it is suitable for fish to spawn. Now I know how to spawn fish and all, but how would I start at a script that finds blocks with the name/Tag "Water" in a certain Radius and count them? I'm not asking anyone to write me a script, I want to learn how to do this for other things I'm going to make for random generation. Maybe if there's a link, or steer me in the right direction. thanks.
if your water tiles have colliders you could use an overlap sphere. http://docs.unity3d.com/Documentation/ScriptReference/Physics.OverlapSphere.html
then check all the hitColliders for the tag and increment a counter when one is found.
p.s. not posting this as an answer because I'm not sure if your tiles have colliders :)
Create new array:
C# - GameObject[] array = GameObject.FindGameObjectsWithTag("Water");
JS - var array : GameObject = GameObject.FindGameObjectsWithTag("Water");
And using Vector3.Distance(a,b) counting the objects which is distance from "mark" is not greater than some number.
So I have got It to count the water blocks in the game, and display the number for me to see, but I need help on the distance thing. Here is my script so far.
var array : Array;
var NumberOfWaterBlocks = 0;
function Update(){
array = GameObject.FindGameObjectsWithTag("Water"); print(array); NumberOfWaterBlocks = array.length;
}
Now how would I be able to incorporate Distance? Ive tried some things but I don't know how to $$anonymous$$us the number if it is out of range, etc.... I don't even know where to begin.
So you can get the list or relevant game objects (per your code above), now you just need to count all of those objects within a certain distance from your spawnPosition... to calculate the distance:
Vector3.Distance(spawnPosition, waterObject.transform.position);
If you were using C# I would include the code for doing the actual counting, but I don't know the JS collection methods.
Ok here it is in C#... hopefully this helps you understand what I mean:
GameObject.FindGameObjectsWithTag("Water").Count(waterObject => Vector3.Distance(spawnPosition, waterObject.transform.position) < spawnRadius);
You would need to include System.Linq. Spawn position is hopefully self explanatory, and spawnRadius is the max distance from spawnPoint to count the water object.
