Spawn wrecks dynamically

Hi,

Is it possible to have a wreck spawned dynamically? What I mean by this is to have a wreck spawn in a certain location under a certain condition. I am looking to have the wreck spawn when I need it to rather than a random time under chance.

So for example, if I walk into an certain area it spawns a wreck?

you'd need to set up some triggers similar to dome protection via the mission sqm

Thanks for the reply Player2. The trigger system I understand, it is the wreck spawning system I don't quite get. I am not a coder, although I have started learning, I don't know which bits to use from the spawnwrecks file in the trigger.
 
I'm sure there is an easier way to do it and I don't know if this would work but you can certainly give it a shot, just make a trigger with that executes spawnWreck.sqf and put this into spawnWreck.sqf.

Now BEFORE YOU DO THIS I have to say I threw this together in five minutes by hacking up server_spawnCrashSite.sqf so I doubt it will work, please backup all of your database and mission file before you try it. I doubt it could mess anything up but better safe than sorry eh? Also I left all the variables in private that I took out so if you wanted to make it cleaner you could go through and find what I took out.

You also need to change any instance of markername to a marker that you named and placed where you want the wreck to spawn.
Let me know if it works, I will probably mess with it later and see if I can come up with something solid for you, I'm just too tired right now. Good luck!

Wow, cool, thank you so much. I will have to try this next week as I am just about to leave for Germany. I am off to Gamescon 2013 in Cologne. I will get back to you ASAP. Thanks again
 
So I have given this a try. So far I have got the trigger working fine in regards to text and area. But I have no wreck spawning or anything in the report. I also have no errors so that is good.

I think I need to test it with a proven something.sqf file to make sure the init statement is working. Will update this post soon.

I have tested the trigger with a working executable sqf. It is fine. It is the spawnWrecks.sqf that is doing nothing - so far.
 
The code I provided was not intended to be used with a trigger if that is what you are doing. For your needs I'd suggest a modification of the animated crashsites script to be used with a trigger. I'm busy right now but tomorrow I'll see if I can make one for you.

That would be awesome if you could. If you are too busy though and it's a hassle then no worries, I was going to start chopping it up and see how it goes.
