Question by subver · Feb 22, 2016 at 05:22 PM · ontriggerenternotworkingglobalvariables

OnTriggerEnter not working when objects speed is from a global variable?

So I have a simple sphere set as player. Rigidbody, kinematic. I've got cubes spawning that move toward the player at x speed. The cubes are Rigidbody's, Kinematic, set to "Is Trigger" and tagged as "Tree"

My code was working fine before I put the Tree speed into a global variable.

This is in my player controller ( which worked just fine before):

 void OnTriggerEnter(Collider other)
     {
         Debug.Log("COLLIDE!");
         if (other.gameObject.CompareTag ("Tree")) 
         {
             Debug.Log("HIT TREE!");
             other.gameObject.SetActive (false);
             count = count + 1;
             SetCountText ();            
         }
     }   


And this is in my Tree movement script:

 private float speed;
 
     void Start () {            
         speed = GlobalControl.TreeSpeed;
     }
     void FixedUpdate() {        
         transform.Translate(0, 0, speed * Time.deltaTime);
     }

It works fine when I set the speed in that script, but when I set the speed to my global variable "TreeSpeed" the OnTriggerEnter no longer works? Any ideas on what I'm doing wrong?

Here is the line in my global script:

 public static float TreeSpeed = 90;

As opposed to setting the speed to 90 in my tree movement script.

Thanks so much!

EDIT: Actually.. weird.. I changed the script back to not use the global variable and it's no longer working. I swear it was working before.. now I'm really confused. Everything was working fine before I put everything in a global variable script!

UPDATE! Ok this is even weirder. When I change the speed from 90 to 100 it works again. Any ideas why this could be? It doesn't seem to work with any 2 digit number as the speed... weird! That's why I thought it was working before the global variable, because it was set at 100 before I changed it to 90.

change the velocity in Fixed Update or use AddForce instead of translating the object.
