Synchronise Problems

[Rak 0]

Hello all,

I've been trying to get into mission making and I can say I've made my first mission. Though, it does work great in Singleplayer, I have some problems in Multiplayer.

The thing is, I have a chopper moving into the base at the start of the mission. It should land and pick us up(my GET IN waypoint is synchronised to his LOAD waypoint, it also has a helipad to land).

What happens in Multiplayer is; it approaches to the base, and when it reaches the "LOAD" waypoint, it immidiately rushes to "TRANSPORT UNLOAD" waypoint. Which in doing leaves my group staring at him on the ground. This only happens when I'm the group leader. When I let the AI do it, it perfectly lands and picks us up. Which confuses me on what to do.

Any ideas?

Sry mate one of lifes great mysteries!

Can never get that to work myself!

Try putting helipads around the area,works sometimes

I have a pair scripts that will solve that problem for you. It actually solves *several* problems with using helicopters in arma.

I've made a Helicopter Tutorial, but only in german language

On the "Load" waypoint you can write as condition NameofHeli flyinHeight 1;

Then place directly at the "Load" waypoint of the heli a "Move" waypoint. In this condition you write {_x in NameofHeli} foreach units group player;

Now the heli arrives his "Load" waypoint, fly in height of 1 meter and wait till the group of the player is in the heli. Then he fly away

Hope this helps too

Regards

Imutep

Thank you guys! I loved ArmA editing but this problem was really bugging me.

It seems singleplayer and multiplayer is a lot different in how arma ArmA plays.

Cheers,

Rak

{_x in NameofHeli} foreach units group player;

That's the basic methodology used in the script above. The thing is that without elaboration, the basic method breaks when someone who's separated from the squad dies. Basically, the group command returns everyone that the squad thinks is alive, just like you see in the command menu at the bottom of the screen. If someone dies where no squadmember sees them, it'll take several minutes for the squad to realize he's missing.

It also fails when the AI gets stuck on the helicopter. This problem is especially noticable on the mi-17 and blackhawks with rocket pods, as they like to get caught up behind the launchers sometimes.

The script above accounts for both problems and solves them.

Right CSL good scripts

Another easy way without scripting is, select your team, click on the incoming chopper and your team will get in when the chopper is landing. But you must be in the chopper before the last man from your team is in. Otherwise the chopper fly away with your team but without you

Hello,

Thank for the help. Though when I put this in the waypoint "On Act." box, I get a "Type Script: Expected Nothing" error. I don't know what to do

[MyHeloName, (leader MyGroupName), desiredFlyOutHeightInMeters] execVM "CSL_HeliPickup.sqf"

Thank for the help. Though when I put this in the waypoint "On Act." box, I get a "Type Script: Expected Nothing" error. I don't know what to do

[MyHeloName, (leader MyGroupName), desiredFlyOutHeightInMeters] execVM "CSL_HeliPickup.sqf"

Those lines "MyHeloName" are usually used as example just as the group name.(I assume this is the case here)

You just need to change them with names you are using in your mission.

And dont forget the ";" at the end of that line.

It's me again

This time, I gave Imutep's method a go. It works when I give names to each group member names like "s1", "s2" and write in the helicopter move waypoint condition box "s1 in UH60 && s2 in UH60 . . ." it works.

But I want to make a MP mission and I want the game to check if all the group members are in, in case some of them died. So, I define my group as "mygroup" and put this in the move waypoint condition box: "{_x in UH60} foreach units group mygroup;". It gives me an error "Type nothing, expected Bool".

I'm about to get this one to work. I just need a little more help :X

[imutep 0]

Try {_x in UH60} foreach units group player;

or

{_x in UH60} foreach units mygroup;

I've got it working with CSL scripts, but I've learned a lot in the progress. Thanks!

Hello,

[MyHeloName, (leader MyGroupName), desiredFlyOutHeightInMeters] execVM "CSL_HeliPickup.sqf"

I know you got it working, but for the benifit of other people, the trouble there is that arma has the capability to return a value with the execVM command.

This means that in the editor, you have to give it a variable to put a potential return value into. If the script returns nothing, I just use garbage as my variable name, like so:

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">CSL_Garbage = [MyHeloName, (leader MyGroupName), desiredFlyOutHeightInMeters] execVM "CSL_HeliPickup.sqf"

Note that programming convention says that you *never* assign "garbage" as a variable name that contains a value you actually intend to keep. Therefore, you always know that garbage is just junk.
