Getting a ghost object to look at the player

I'm trying to get a camera to follow the player when he enters a sector, but my puny brain is far to small to understand the equation I need to do this! Here's what I have thus far (don't mind the stupid equation I tried [http://forums.massassi.net/html/smile.gif]

)

Code:

# Jedi Knight Cog Script
#
# Filename.COG
#
# Description
# 
#
# This Cog is Not supported by LucasArts Entertainment Co

symbols

sector		camersec		linkid=1
thing		camera			
thing		player			local

vector		playerpos		local

message 	startup
message	entered
message	pulse
message 	exited	

end

# ========================================================================================

code
startup:
	player = GetLocalPlayerThing();

entered:
	if(GetSenderRef() == camersec) {
		SetCameraFocus(0,camera);
		SetPulse(.01);
	}
	return;
pulse:
	playerpos = (GetThingPos(player) - GetThingPos(camera));
	SetThingLook(camera,playerpos);

exited:
	SetPulse(0);
	

# ........................................................................................

end

any help is appreciated!

You were missing a few Return;'s that would cause code sections to run together.

Also I've always seen vector subtraction done using the VectorSub() cog verb.

Try this:

Code:

# Jedi Knight Cog Script
#
# Filename.COG
#
# Description
# 
#
# This Cog is Not supported by LucasArts Entertainment Co

symbols

sector     camersec     linkid=1
thing      camera
thing      player       local
vector     playerpos    local

message    startup
message    entered
message    pulse
message    exited

end

# ========================================================================================

code

startup:	
                player = GetLocalPlayerThing();
                Return;
entered:
                if(GetSenderRef() == camersec)
                {
                     SetCameraFocus(0,camera);
                     SetPulse(.01);
                }
                Return;
pulse:
                playerpos = VectorSub(GetThingPos(player), GetThingPos(camera));
                SetThingLook(camera,playerpos);
                Return;
exited:
                SetPulse(0);
                Return;
