How to display a variable in a task?

[JacobJ 10]

Hey all

I have a script that returs a number and that number is put to a variable called mst.

mst = 10;

How would I get that number into a task? This doesnt seem to work:

	tskMST = player createSimpleTask ["Step"];
tskMST setSimpleTaskDescription ["Step: mst", "Step: mst",  "Step: mst"];

/Jacob

[celery 8]

[format ["Step: %1","Step: %1","Step: %1",mst]];

I get and error: Error 1 elements provided, 1 expected.

What does this mean?

Probably wrong use of format.

_str = format ["Step: %1",mst];

..settaskdesc [_str,_str,_str];

[celery 8]

Sorry, the quotes confused my simple mind.

[format ["Step: %1",mst],format ["Step: %1",mst],format ["Step: %1",mst]];

Okay the two different type result in this: Shuko's version doesnt give the number, but "scalar" and Celery, yours give "any" instead of the number. How can this be?

[celery 8]

mst = 10;

tskMST = player createSimpleTask ["Step"];

tskMST setSimpleTaskDescription [format ["Step: %1",mst],format ["Step: %1",mst],""];

Yes but mst isnt defined. It was just an example. Through the mission numbers gets added to mst, so I want to display the current number mst represents. The mst variable is comming from another script. It doesnt seem to work to put this to publicVariable. Still I get the scalar output and not the number that mst represents.

If a variable isn't defined before it's used somewhere, naturally it doesn't work. If you want the task to update its description, you have to loop tskMST setSimpleTaskDescription [format ["Step: %1",mst],format ["Step: %1",mst],""]; throughout the mission.

Okay after searching around here on the forum I found out that it could be a timing problem. I tried to wait a few seconds to execute the tskdes script and now it did display the number very nicely. It is an interesting thought, to have a loop to update this number. A simple while {true} do {sleep 5; bla blab bla would be fine right?

I have a few loops in my mission, how many loops can be allowed, before the server begins to lag? Is that even an issue?

A loop like that should work.

There is no limit to loops and scripts unless they're scripted in a way that puts stress on the cpu (loops without sleep or the sleep is needlessly fast).
