Unknown crash bug of my code

[r3v3n93]

Code: Select all

virtual state A_SCLook() //called in "Spawn"
	{
		A_Look();
		if(CheckProximity("Doomplayer", 1000, 1, CPXF_SETMASTER) && !target)
		{
			A_Log("I set my master, and Im following him");
			target = master;
			return ResolveState("SeeFriend"); //when the actor acquires player, it'll set the player to target and will send to this special See state. Not associated with the bug. I tested it.
		}	
		return State(null);	
	}
	
virtual State A_SCChase(bool is_melee_state_there = false) /called in "See"
	{
		A_Log("Hi, I'm new to A_SCChase.");
		if(!target)
		{
			return ResolveState("Spawn");
		} //For some reason, sending the actor to Spawn state from Pain state when the actor is following the player crashes. It's either this block's problem or the A_SCLook's Problem
		if(target && master)
		{
			if((target == master))
			{
				A_Log("Im Chasing");
				return ResolveState("Seefriend");
			}
			else if(target != master)
			{
				A_Log("Trying to pursuit enemy.");
			}
		}
		
		A_Log("TEST");
		bSTANDSTILL = false;

		//A_LookEX(0, 1, MaxTargetRange, MaxTargetRange, 360, "Missile");
		
		if(is_melee_state_there == true && Distance2D(target) <= MeleeRange && target)
		{
			return ResolveState("melee");
		}

		if(target && Distance2D(target) <= MaxTargetRange)
		{
			return ResolveState("Missile");
		}
		
		A_FaceTarget();
		NewChaseDir();
		return State(null);	
	}	
	
Pain:
    	PLAY G 4
		{
			if(target)
			{
				if(master)
				{
					if(target == master) //when the actor is following the player...
					{
						A_Log("I cleared my target");
						A_ClearTarget();
					}
				}
			}	
		}
    	PLAY G 4;
    	Goto See;	
	

This actor is a friendly monster and has an algorithm to follow player whenever they don't have hostile targets. If the actor gets hurt, if the actor is following the player, it will clear the pointer in where the player was defined for compatibility with See state.
Here's the issue. When player attacks the actor on purpose when the actor is following the player, the game just crashes without any crash logs. Any solutions?

Your code cannot be run as-is. Please provide a runnable example for testing. As of now, I cannot be certain, but it looks like you may be triggering a condition where your code starts jumping back and forth between two states continuously and without any delay between the jumps. Or it could be a stack overflow - these are the two most common scenarios that GZDoom is not able to handle gracefully.
