Random spawn for fortifications, road blocks etc

[Barabara 10]

I'm trying to create a mission with random objectives and random ao's, how do I create fortified positions and road blocks in the editor (complete with personell manning them) that are then moved to one out of several pre-defined locations when the mission begins?

[Barabara 10]

No one with a good idea how to accomplish this? It's the last big step towards creating missions with some decent replayability.

[semiconductor 309]

You can use setPos to set object's position and setDir to set object's direction. Create an array of predefined positions, pick one of them with "random" command and then move roadblock on that position.

[iceman77 18]

You need to look into the object grabber from Arma2. You can create custom compositions (camps, roadblocks.. anything) and place them anywhere on the map, facing any direction. You'll need to edit things a tad bit though & take out any setVehicleInit / processInitCommands (as they are not supported by Arma3).

This works like a charm and i would recommend it to anyone who likes making compositions.

iceman77 ". You'll need to edit things a tad bit though & take out any setVehicleInit / processInitCommands (as they are not supported by Arma3). ". hmm can i just delete those lines or what, maybe you can post your edited working versions of the script.. theyre not that big right??

yeah just comment them out. Should just be 2 lines.

Well I can help with the roadblock locations. I wrote a script that can create a working roadblock at a marker location placed in the editor.

[hansson0728 12]

great stuff iceman :) thumbs up

[Larrow 2800]

Whats wrong with BIS_fnc_objectsGrabber & BIS_fnc_objectsMapper under functions/spawning do they not work properly or something?? have not tried them myself.

[hansson0728 12]

is it possible to hack it to eanble placing units?? just standing units that will guard and fire, no waypoints and stuff ?? i don't want to use the bis task defend function i want more control.

-----------------------------

Update, :)

------------------------------

i did some modifications to the object grabber so it can grab soldiers and their direction and stance if anyone is interested...

Example mission.

check the custom radio commands, you can use 0-0-4 to place a soldier at your current location.

with this you can use any RTE like MCC or virtual training space to build your base or whatever, the just walk around the base placing soldier where ever you want, just by standing in the spot facing the direction with the stance you prefer and spawn in a soldier right there. then grabb it all, the mapp it all

hope this is something for someone, thank you, any improvements are welcome, just PM me.

Big ups for the original authors of the scripts (objectgrabber/Objectmapper)

Hadn't even realized they existed. Been using those scripts lol.
