Destroying Instantiated Obect Problem

Questions & Answers
1

So I have this script that when I press t it spawns a wood plank in front of you that you can place down. However I can’t get the board to go away when you press the same button. Any ideas on how I could do this? Here’s the script:

if (Input.GetKeyUp("t") && woodAvailable > 0) {
		
			if ( buildingMaterial == true) {
				
			Destroy(obstacleToBuild);
			buildingMaterial = false;
				
			}
			
			
			
			if (buildingMaterial == false){
			
			playerPosition = transform.position;
			playerRotation = transform.rotation;
			
			obstacleToBuild = Instantiate(woodPlank, myGamobject.transform.FindChild("Main Camera").position + 3f * Vector3.forward, myGamobject.transform.FindChild("Main Camera").rotation) as GameObject;
			obstacleToBuild.transform.parent = myGamobject.transform.FindChild("Main Camera");
			buildingMaterial = true;
		
				
			}
		
		
		}

if (Input.GetKeyUp(“t”) && woodAvailable > 0) {

     if ( buildingMaterial == true) {

     Destroy(obstacleToBuild);
     buildingMaterial = false;

     } else {

     playerPosition = transform.position;
     playerRotation = transform.rotation;

     obstacleToBuild = Instantiate(woodPlank, myGamobject.transform.FindChild("Main Camera").position + 3f * Vector3.forward, myGamobject.transform.FindChild("Main Camera").rotation) as GameObject;
     obstacleToBuild.transform.parent = myGamobject.transform.FindChild("Main Camera");
     buildingMaterial = true;

     }

   }
