ExecVM from triggers

[felipechapmanfromm 5]

How would I do an execVM from inside a trigger. This does not work

_trg = createTrigger ["EmptyDetector", getPos _casSpawn];
_trg setTriggerArea [20, 20, 10, false];
_trg setTriggerActivation ["CIV", "PRESENT", true];
_trg setTriggerStatements ["this", "execVM "mount.sqf";", "hint 'Test'"];

and also how do I mount the AI into the nearest vehicle as cargo when it is triggered.

"execVM "mount.sqf";"

 

this bit needs  to be like this

 

"execVM 'mount.sqf';"

 

" " inside " " need to be ' '

Thanks

I have change the code but it tell me undifined variable in expression

here it is

_trg = createTrigger ["EmptyDetector", getPos _casSpawn];
_trg setTriggerArea [20, 20, 10, false];
_trg setTriggerActivation ["CIV", "PRESENT", true];
_trg setTriggerStatements ["this", "null = [_casSpawn,_casPos,_casGroup] execVM 'mount.sqf';", "hint 'Test'"];

These variables are undefined within the scope of your triggers activation code. You have to remember that the STRING representing your triggers activation code is deferred to run at some point in the future (when the trigger is activated) and as such knows nothing about any local variables that where present at the time you set the triggers activation code.

You can also do:

"[] execVM ""test.sqf"";"

yeah it was late and i didnt want to add that way. The way i wrote it would of look weird

[HazJ 1288]

Yeah, I know. Most people use the way you said. I prefer double " that's all. Just thought I'd share the other way.

[Chuc 83]

i use them like this

 

hint parseText format['<t size=""1.10"" font=""PuristaMedium"" color=""#13F03C"">You are out of contamination</t>'];

 

Looks nicer i think

I've fixed the variable problem and the execVM but now i need to know how to pull variables from the mission editor, I have made a heli that  has the var name heli1, how do i get heli1 into my sqf files

Just use heli1 giving it a variable name automatically creates a global variable of the same name that is a reference to your object.

Thanks i will try that now

_trg setTriggerStatements ["this", "null = [_casSpawn,_casPos,_casGroup] execVM 'mount.sqf';", "hint 'Test'"];

 

 

Just for the record, if a trigger is created in a script and local variables need to be used in the activation call of the trigger, all forms of parsing variables into strings can be used:

 

private["_casSpawn","_casPos","_casGroup","_trg"];
// Setting _casSpawn,_casPos,_casGroup to some values
_trg = createTrigger ["EmptyDetector", getPos _casSpawn];
_trg setTriggerArea [20, 20, 10, false];
_trg setTriggerActivation ["CIV", "PRESENT", true];
_trg setTriggerStatements ["this", format ["null = [%1,%2,%3] execVM 'mount.sqf';",_casSpawn,_casPos,_casGroup], "hint 'Test'"];

This will parse the variables into the string and it will become a static expression like "null = [someObject,[2312,54234,234],SomeGroup-1-2-West] execVM 'mount.sqf';" that can be called uncoupled from the script creating the trigger.

In some cases, the str command needs to be added to the parameters of format to have the variables added correctly (needed for string to have correct escaping of quotes).

 

When debugging this, it is good to make your called script (mount.sqf) print all parameters and their type into the rpt or chat to check if everything worked as expected.

You know, sometimes my own ability to overlook the obvious is just astounding. Your post solved a big problem I was having back in A2 - I was on the right track, but was consistently losing sight of the actual issue. Too late to fix that old problem, but you just made something "click" for me. Thanks, I love it when that happens!

Thanks for all the help, i have solved it now
