Hi there,
I have a smiluation and want to build structures in-game. And I want the surrounding trees to be removed when placing a building nearby.
Problem is that my current solution actually does remove the trees within a certain radius. But the game freezes for a few seconds, since there are so many trees.
The code looks similar to this:
TreeInstance[] trees = Terrain.activeTerrain.terrainData.treeInstances;
ArrayList newTrees = new ArrayList();
Vector3 terrainDataSize = Terrain.activeTerrain.terrainData.size;
Vector3 activeTerrainPosition = Terrain.activeTerrain.GetPosition();
float distance;
foreach (TreeInstance tree in trees )
{
distance = Vector3.Distance(Vector3.Scale(tree.position, terrainDataSize)
+ activeTerrainPosition, currentObject.transform.position);
if (distance > 20) {
newTrees.Add(tree);
}
}
Terrain.activeTerrain.terrainData.treeInstances = (TreeInstance[])newTrees.ToArray(typeof(TreeInstance));
do you have any suggestions how I might be able to do this faster?
