Get transform component from all gameobjects with tag
What I am trying to do is that all gameObjects with the tag of "Waypoint" are added to an array of transforms. The only problem is that I can't seem to be able to add them to the transform array as I am not able to access their transform component and assign it per object to the transform array.
private var wayPoints : Transform[];
wayPoints = GameObject.FindGameObjectsWithTag("Waypoint");
//Add the transform component of each object to the wayPoints transform array
var wayPointsArray = new Array(wayPoints);
for(var point : Transform in wayPointsArray){
//Do pathfinding stuff
}
Try this:
import System.Linq;
Then get your components like this:
var wayPointTransforms = GameObject.FindGameObjectsWithTag("Waypoint").Select(function (go) {return go.transform;}).ToArray();
Had been looking for an answer all day - Just saved me alot of frustration. Thanks.
Cool stuff Linq - can do a lot of cool things with lists/arrays :)
wayPoints itself is an array of the gameobjects, so why assign a new array for it? just use wayPoints = GameObject.FindGameObjectsWithTag("Waypoint");
for(var i = 0; i < wayPoints.length; i++)
{
//do pathfinding stuff with point = wayPoints[i]
}
I require the Transform component so I can access the position of each point.
for(var point : Transform in wayPointsArray){}
Usualy I would have to add all points in the inspector but I am looking for a more efficient and automated way by just letting unity look for all objects that are taged as waypoints and them adding them to the array.
