Display a map marker via trigger

[ledhead900 10]

I am trying to use a trigger to make a couple map markers used as a visual zone border.

The mission I am working on has the squad move up towards a town, you get a new task and then I needed a couple of pre placed map markers to become visible. The markers must remain hidden until this trigger is tripped.

I thought the below method may work, I have not tried it yet.

1. Place the trigger down grouped to player, sync the trigger to a map marker?

Other possible method is using the INIT section with a hide and show function synced to the trigger much like how get hostages to work.

Check out marker commands like setMarkertype and setMarkerAlpha. You can have the marker be of the 'empty' (invisible) type initially, but then use the trigger to set it to a visible type. Or set its alpha to 0 on startup, then set it to 1 when you want it visible.

That should do it both those methods you posted look good, thanks. Eventually I won't have to ask so much newbie stuff lol

Or you can create a Marker tied to an object.

Works great for things that are on-the-move.

Change Sleep to update how fast you want.

1. Setup Trigger how you want.

2. In On Act box activate the script:

nul=[]execVM "crashsite.sqf"

crashsite.sqf

_markerDP1 = createMarker["F18jet1Marker",getPos F18jet1];
"F18jet1Marker" setMarkerShape "ICON";
"F18jet1Marker" setMarkerType "hd_objective";
"F18jet1Marker" setMarkerColor "ColorRed";
"F18jet1Marker" setMarkerText "CSAR - F-18 CRASH SITE";
"F18jet1Marker" setMarkerAlpha 1;
[] spawn {
while{not isnull F18jet1} do {"F18jet1Marker" setMarkerPos getPos F18jet1; sleep 999;};
};

};

Oh nice, so this is for things that move around so say I wanted the marker to be positioned on a dead player I would setup the trigger to check if he was dead and then the above would put a marker where the object was at the time?. I don't have a use for that right now but thanks.

I ended up with the this code tied to the trigger "On Act" and the trigger group bound to the team leader and set to groups of units works well for my purposes. When the group in question walk over the trigger it counts down from 5 and then displays circles in yellow just as I wanted.

"Zone1" setMarkerBrush "SOLID";
"Zone2" setMarkerBrush "SOLID";
"Zone1" setMarkerAlpha 0.5;
"Zone2" setMarkerAlpha 0.5;
"Zone1" setMarkerShape "ELLIPSE";
"Zone2" setMarkerShape "ELLIPSE";
"Zone1" setMarkerSize [200, 200]; 
"Zone2" setMarkerSize [100, 100];
