Limit a trigger to certain units in MP

[McSpeed 1]

hmm that would be too easy but it doesnt work unfortunately.

That was one of the first things i tried.

The gatelock script i am using

 lock = true;

while {lock}
do {
gate2 animate ["Bargate",1];
sleep 0.01;
   }; 

does work... once.

as soon as a pilot opens the gate the lock is broken, i tried to re-initiate it by adding execvm "gate.sqf" to the deactivation line, but no joy.

the script Pelham has posted there seems more complex than the one i am using, but since i dont understand what he means in that last paragraph (public variables) i cant apply and test this one yet.

It's not a simple thing to understand and it still gives me a headache sometimes, you need to read up on it:

Variables are only visible in certain areas (namespaces) of the game. This prevents name conflicts between different variables in different scripts.

There are three namespaces:

local: A variable is only visible in the script in which it was defined.

global: A variable is visible on the whole computer where it is defined.

public: A variable is broadcasted over the network and visible on all computers connected to the network.

ok just to make sure i actually understand what it is i am doing here :)

on Act: [color="#FF0000"]varlockg1=0;[/color] 
on Dea:[color="#FF0000"] varlockg1=1;[/color]

those lines call for an action as defined in the script, correct?

the action is defined here? (in the first line of the script)

[color="#FF0000"]varlockg1=1;[/color] 

trying to understand so ill translate it into english:

while{true}do{
   if((gate1 animationPhase "Bargate" [color="#FF0000"]< 1[/color]) && (varlockg1==1))[color="#0000CD"]then{gate1 animate ["Bargate",1]};[/color]
sleep 0.1;
};

while the defined state is active (true) close the gate

then{gate1 animate ["Bargate",1]};

provided that the gate is already closed AND the action is being called

if((gate1 animationPhase "Bargate" < 1) && (varlockg1==1))

am i getting this right?

what i definately dont understand are these 2 things:

< 1

and

sleep 0.1;

oh and why there are 2 "==" instead of just one.

sorry for being so difficult now, but if i dont actually understand what i am doing i will never learn :)

You use == when you want to do "if a is equal to b".

You use = if you want "a becomes same as b".

now it makes sense , of course. the difference between a definition and a comparison . thank you :)

It's a global variable that is set to either 1 or 0 depending on the activation of the trigger.

1 is locked, 0 is unlocked, you will see the way I set it up is when the right kind of AI walks into the trigger it stops that locking while loop.

You always sleep in a while loop or it repeats too many times a second and crashes the game. We are asking it to check all that every 0.1 of a second.

for the rest look at the scripting command index.

yay it now works just as it should \o/

thanks to you guys and mousetrap.:)

he understood what you were talking adout ( i didnt get that the public variable line was meant literally :) )

So he implemented it for me and now , looking at it, it does indeed make perfect sense.

When it comes to code its like i have a peas for brains sometimes :)

thanks to you all.

to sum this one up:

place a gate, name it gate2 (in this case, else replace a the following "gate2" entries with whatever name you chose)

enter in the gates init:

gate2 animate ["Bargate", 1]; this addEventHandler ["HandleDamage", {false}];

locking gates!

Lock the gate :

add this to init.sqf:

 [] execVM "gatelock.sqf";

create a text file gatelock.sqf:

varlockg1=1;
while{true}do{
   if((gate2 animationPhase "Bargate" < 1) && (varlockg1==1))then{gate2 animate ["Bargate",1]};
sleep 0.1;
};

set the trigger and fill out like so: (ignore the sold1 playmove line, it refers to a guard next to the gate)

thats it :)

problem solved.

thanks again to all who helped.
