Question by QTate · Jun 19, 2016 at 08:30 PM · ontriggerenterontriggerexit

Can someone please tell me why this code isn't working?

Hello everyone,

Hopefully I'll get a video link that could actually show how to script something similar to what I have in mind. I'm very new to Unity and scripting is still very challenging for me if it's not too much to ask could someone please help me understand why this code isn't working. I'm simply trying to have a block rest on a plate to keep a ceiling up, but if the bock is removed from the plate then the ceiling will lower. I can't understand how something this basic is having me up for several days reading the Unity manuals and searching on Youtube for a similar tutorial. Any assistance would be greatly appreciated.

 using UnityEngine;
 using System.Collections;
 
 public class controlCeiling : MonoBehaviour
 {
     public GameObject SpikeCeiling;
 
     private Animator CeilingDown;
 
     private bool CeilingLowering;
 
     // Use this for initialization
     void Start ()
     {
         CeilingDown = SpikeCeiling.GetComponent<Animator>();
     }
     
     // Update is called once per frame
     void Update ()
     {
         CeilingLowering = CeilingDown.GetBool("LoweringCeiling");
     }
 
     void OnTriggerEnter (Collider entity)
     {
         if (entity.tag == "LBM_Cube")
         {
             print("The cube is on the pressure plate");
         }
     }
 
     void OnTriggerStay (Collider entity)
     {
         if (entity.tag == "LBM_Cube")
         {
             CeilingDown.SetBool("LoweringCeiling", true);        }
     }
 
 
 }

Hello! From what i understand you want to set the "LoweringCeiling" to false, when the Block is outside the trigger correct? you might want to set it to false in "OnTriggerExit" see https://docs.unity3d.com/ScriptReference/Collider.OnTriggerExit.html

Something like this, might help:

 void OnTriggerExit(Collider entity){
     // Set the bool to false, when the block leave the trigger area
     if (entity.tag == "LB$$anonymous$$_Cube") {
         CeilingDown.SetBool("LoweringCeiling", false);
     }
 }

And i don't think you need to set CeilingLowering, everytime on update.

Hope this help! cheers!
