[FIXED?]World Crash - ProcessMovement()

[John Adams]

I was in the Frostfang zone and went to the GM Hall to be in a zone without spawns. After being in there for a few minutes, and talking about stats in IRC, I noticed my world crashed out behind me. I'm assuming this is an NPC "follow" issue, because where it broke I don't think that has anything to do with looking at stats in the Character options

Zone was not shutting down yet or anything.

Code:

Code: Select all

void Spawn::ProcessMovement(){
	// Skip players
	if (IsPlayer() || GetHP() <= 0)			<== I didn't do it, I swear!
		return;

	MMovementLoop.lock();
	if (following && m_followTarget) {
		if (!IsEntity() || (!((Entity*)this)->IsCasting() && !((Entity*)this)->IsMezzedOrStunned())) {
==> here		if (GetSpeed() > 0) {
				CalculateRunningLocation();
			}

m_followTarget was stuff like: "changed = <Unable to read memory>"

I think that HP check was put in because of a bug where sometimes corpses would follow you around eerily

[John Adams]

I just meant I am IsPlayer() so it wasn't me

It was below that check, so had to be NPC movement related.

This looks like the pointer went invalid as well so wth is going on.

If the possible fix for the FaceTarget() crash works it should also solve this crash.
