how to start "spline controller" with trigger?
I set the script spline controllers "on a character" Player2, and everything works. but how to activate the script with a trigger
enum eOrientationMode { NODE = 0, TANGENT }
var SplineParent : GameObject; var Duration : float = 10.0; var OrientationMode : eOrientationMode = eOrientationMode.NODE; var WrapMode : eWrapMode = eWrapMode.ONCE; var AutoStart : boolean = true; var AutoClose : boolean = true; var HideOnExecute : boolean = true;
private var mSplineInterp : SplineInterpolator = null; private var mTransforms : Array = null;
@script AddComponentMenu("Splines/Spline Controller")
function OnDrawGizmos() { var trans : Array = GetTransforms();
if (trans.length < 2) return;
var interp = new SplineInterpolator(); SetupSplineInterpolator(interp, trans);
interp.StartInterpolation(null, false, WrapMode);
var prevPos : Vector3 = trans[0].position; for (c=1; c <= 100; c++) { var currTime:float = c Duration / 100.0; var currPos = interp.GetHermiteAtTime(currTime); var mag:float = (currPos-prevPos).magnitude 2.0; Gizmos.color = Color(mag, 0.0, 0.0, 1.0); Gizmos.DrawLine(prevPos, currPos); prevPos = currPos; } }
function Start() { mSplineInterp = gameObject.AddComponent(SplineInterpolator);
mTransforms = GetTransforms();
if (HideOnExecute) DisableTransforms();
if (AutoStart) FollowSpline(); }
function SetupSplineInterpolator(interp:SplineInterpolator, trans:Array) : void { interp.Reset();
if (AutoClose) var step : float = Duration / trans.length; else step = Duration / (trans.length-1);
for (var c:int = 0; c < trans.length; c++) { if (OrientationMode == OrientationMode.NODE) { interp.AddPoint(trans[c].position, trans[c].rotation, step*c, Vector2(0.0, 1.0)); } else if (OrientationMode == OrientationMode.TANGENT) { if (c != trans.length-1) var rot : Quaternion = Quaternion.LookRotation(trans[c+1].position - trans[c].position, trans[c].up); else if (AutoClose) rot = Quaternion.LookRotation(trans[0].position - trans[c].position, trans[c].up); else rot = trans[c].rotation;
interp.AddPoint(trans[c].position, rot, step*c, Vector2(0.0, 1.0));
}
}
if (AutoClose) interp.SetAutoCloseMode(step*c); }
// We need this to sort GameObjects by name class NameComparer extends IComparer { function Compare(trA : Object, trB : Object) : int { return trA.gameObject.name.CompareTo(trB.gameObject.name); } }
// // Returns children transforms already sorted by name // function GetTransforms() : Array { var ret : Array = new Array();
if (SplineParent != null) { // We need to use an ArrayList because theres not Sort method in Array... var tempTransformsArray = new ArrayList();
var tempTransforms = SplineParent.GetComponentsInChildren(Transform);
// We need to get rid of the parent, which is also returned by GetComponentsInChildren...
for (var tr : Transform in tempTransforms)
{
if (tr != SplineParent.transform)
tempTransformsArray.Add(tr);
}
tempTransformsArray.Sort(new NameComparer());
ret = Array(tempTransformsArray);
}
return ret; }
// // Disables the spline objects, we generally don't need them because they are just auxiliary // function DisableTransforms() : void { if (SplineParent != null) { SplineParent.SetActiveRecursively(false); } }
// // Starts the interpolation // function FollowSpline() {
if (mTransforms.length > 0) { SetupSplineInterpolator(mSplineInterp, mTransforms); mSplineInterp.StartInterpolation(null, true, WrapMode); } }
SOLVED! i've disabled the "spline controller" and i've create another script attached at the trigger
Code:
function OnTriggerEnter (collision : Collider)
{
if (collision.gameObject.tag == "Player")
{
GameObject.Find("objectwithsplinecontroller").GetComponent("SplineController").enabled=true;
}
}
When I attempted to set the enabled state in a helper function I got the error "set_enabled can only be called from the main thread." But it worked when I put it in the update function. (just incase this info is useful to others)
If this script does what you want it to do, but you want it to not work from the beginning, but later, you can add it to the gameobject trough script (initiated by a trigger) using AddComponent(name_of_your_script)
I've tried this solution and when I try to trigger the script not in the start funtion it says: "set_enabled can only be called from the main thread."
