Raycast target line of sight

Hello, I seem to be in a bit of a pickle with a piece of code. I am trying to get the turret to only shoot when target is in line of sight, In my tests i have a target on a path to cross a turret, in between them both is a wall, I don’t want the turret to look at or even shoot at the target until its in the light of sight, Instead, My turret shoots through the wall GRR. please check this code and slap my hands on what i did wrong, Thanks.

public override void Update(){
		base.Update();
		
		if(turretObject!=null && target!=null && !stunned){
			//~ if(animateTurret==_TurretAni.YAxis){
				Vector3 targetPos=target.thisT.position;
				targetPos.y=turretObject.position.y;
				
				Quaternion wantedRot=Quaternion.LookRotation(targetPos-turretObject.position);
				turretObject.rotation=Quaternion.Slerp(turretObject.rotation, wantedRot, 15*Time.deltaTime);
				
				if(Quaternion.Angle(turretObject.rotation, wantedRot)<45) targetInLOS=true;
				else targetInLOS=false;
			//~ }
		}
		RaycastHit hit;
        if (Physics.Raycast(thisT.position, target.thisT.position, out hit)&& hit.transform.tag == "wall")
			targetInLOS=false;
		print("Raycast hit: " + hit.transform.tag);
				
	}

Your Raycast is not right. For this form of Raycast, the first two parameters are a position and a direction. You have two positions. Replace the second parameter with target.thisT.position - thisT.position; So it would look like:

if (Physics.Raycast(thisT.position, target.thisT.position - thisT.position, out hit)&& hit.transform.tag == "wall")

Note the ‘target.thisT.position’ looks strange. Maybe it should be ‘target.position’ or ‘target.transform.position’?
