Title: blowing up bridges
Post by: BensTooCool on 04 Mar 2007, 23:59:54

I'd like to know how to blow up a bridge in Armed Assault, I played a mission in the campaign where you blow the bridge in Dolores and I thought if i extracted that mission from the campaign I could figure it out but when I opened it the editor it didn't show anything ;/

Have you tried using a good old fashioned bomb? Hardliners prefer the IED...

To make a BOMB:
Place an empty object in your mission at the base of the bridge you plan to destroy. Name the object TARGET.
Then create an trigger and choose how you want to activated it, for example we'll use Radio Alpha.
In the the trigger's Activation Field put the following:

Code: [Select]

BOMB = "Bo_GBU12_LGB" createVehicle getpos TARGET;
Start your mission, activate radio alpha and watch it light up the bridge :)

To make a your BOMB an IED:
Follow the above instructions and save your mission.
Then access the mission.sqs file in the mission's folder and use the Ctrl+F feature to find the object named TARGET.
Once you've located your object, change the object vehicle name to bomb.
Then save and reload the mission and your bomb now looks like a pretty IED :)

Code: [Select]

id=0;
side="EMPTY";
vehicle="bomb";
leader=1;
skill=0.600000;
text="TARGET";
(Another serving suggestion is to name your player TARGET  :D)

The above is proberly the hardest way to achieve your objective Ben, but it does work.
Hope it helps.

Well in the mission I'm making the idea is you blow the bridge up using satchel charges stopping the enemy from chasing you.

Not much editing needed for that to work. Just make sure that the player has enough satchels available and he knows where to place them. You could weaken the bridge with setDamage but I don't think that that's what you want.

Anyway the correct position to place the satchels is marked on the attached image. I placed three satchels.

I just had a brainwave, If I place a hidden object in the area of the satchel charge then when you detonate and the object is destroyed i can make a trigger set the bridge section to setdamage 1 thus destroying the bridge.  :)

I managed to get it working in Operation Flashpoint but one bit won't work in ArmA.

Triger
Condition: not alive <name>
Activation: (object <number>) setDamage 1   <--- Works in ofp but not in ArmA

anyone know how to make it work?

One question... how can you link a bridge to a trigger? I was able to do this with buildings but I can't seem to link a bridge to a trigger. Can this be done?

Well if you select ShowIDs then it should show the ID numbers for each section of bridge, In operation flashpoint I just took one of the IDs then in the trigger activation field i put "(object <ID>) setdamage 1" this basically will destroy a section of the bridge....but as i say it wont work in ArmA

Actually, the method does, the command object does not..

This is what was learned in couple of threads (here (http://www.ofpec.com/forum/index.php?topic=28760.0) and here (http://www.ofpec.com/forum/index.php?topic=28759.0)) here some time ago:

• - Due to the streaming technology the command object doesn't work..
• - You can find any of those objects using someposition nearestObject objectID
  This causes trouble if the object is outside of the 'streamed up' range, probably outside the viewdistance range, the game freezes for a quite long time (half a minute in one of my tests) because it has to 'stream up' the object you are looking for.
  (Obviously one of the things I speculate in one of those threads is rediculous, of course the object ID is in the memory, it's more like that the object that it points to doesn't exist before it's 'streamed up' ::) )

Anyway, if the bridge is in player's viewdistance range you can use the method BensTooCool suggests, only modified to work in ArmA by using the nearestObject command:

Code: [Select]

((position player) nearestObject objectID) setDamage 1

thanks h- that worked a treat but I have one more thing I hope you can help me with, how would I edit that line to put it in a condition field so I can tick off an objective when the bridge is destroyed?

Title: Re: blowing up bridges
Post by: h- on 06 Mar 2007, 23:13:10

Code: [Select]

!alive ((position player) nearestObject objectID)
At least that worked for me..
