I need the knight to patrol from one ghost to another, ina function that can be turned on and off, but without disrupting the flames:

Code:

# 03_sneaky.cog
# [Grismath]
# 5.27.04
#
# NEW: 8.29.04: Loop through all surfaces to find ones
#  with a custom flag, then set those to geo4, and
#  scroll them down.
#
#  Thanks go to LKOH_SniperWolf for the rain code.

Well, this should do it. Once again, untested. But, hopefully right. The # comments should probably be removed, but I wanted to make it easier to tell which each does.

You can add more ghosts as needed, just don't forget to make sure numPositions is set appropriately. It should be the number of actual ghosts used (remembering ghost0 is 1)

moveSpeed determines the AI's movespeed.

willLoop; this is basically a boolean, 0 for false, anything greater than 0 for true.
If willLoop is true, when the AI gets to the last ghost position, he'll move from there to the first ghost. This would be what you'd want if you wanted a circular path.
If false, when the AI gets to the last position, it will go from there to the second to last ghost, on back towards the first. When at the first, it will start back. Basically this will cause it to go back and forth along them, more useful if it's a straightline path.

Code:

thing     knight
thing     ghost0
thing     ghost1
thing     ghost2
thing     ghost3
thing     ghost4

int       on = 0       local

int       numPositions
#set this equal to the number of ghosts used
#IE ghost#, take that # + 1...

int       willLoop
#set this to 1 or greater, if you want it to
#go from the last used ghost 

int       i2            local

flex      moveSpeed

message   knightPatrol



knightPatrol:
if(on == 0){
    on = 1;
}else{
    on = 0;
    AISetMoveThing(knight, ghost0);
    AISetMode(knight, 0x0);
}

while(on){
    AISetMoveSpeed(knight,moveSpeed);
    AISetMode(knight,0x1);
    if(willLoop){
        for(i2 = 0; i2 < numpositions; i2 = i2 + 1){
            AISetMoveThing(knight, ghost0[i2]);
            AISetLookPos(knight, GetThingPos(ghost0[i2]));

            //This makes the code wait till the AI is within a reasonable distance
            //to the ghost position before letting it go to the next one.
            while(VectorDist(GetThingPos(knight),GetThingPos(ghost0[i2])) > .05){
                Sleep(.1);
            }
        }
    }else{
        for(i2 = 0; i2 < numpositions; i2 = i2 + 1){
            AISetMoveThing(knight, ghost0[i2]);
            AISetLookPos(knight, GetThingPos(ghost0[i2]));

            while(VectorDist(GetThingPos(knight),GetThingPos(ghost0[i2])) > .05){
                Sleep(.1);
            }
        }
        for(i2 = numpositions - 1; i2 > -1; i2 = i2 - 1){
            AISetMoveThing(knight, ghost0[i2]);
            AISetLookPos(knight, GetThingPos(ghost0[i2]));

            while(VectorDist(GetThingPos(knight),GetThingPos(ghost0[i2])) > .05){
                Sleep(.1);
            }
        }
    }
}

Return;

Let me know how it turns out.

That while statement with the VectorDist should all be on one line. The forum just word-wrapped it.
