Evening.

Im trying to create a simple "calculator" for use in a planned multiplayer artillery system. I want to be able to move the spot where the artillery hits at custom, so i thought i might start out with a simple variable called sum.

I want to be able to increase and decrease the value of the variable "sum" by pressing two triggers_use named inc and dec, but i just cant get it to work.

Any ideas?

Well, this is my script so far. All it does is showing the current sum when you press a button.

Quote:
main()
{

thread output();

}
output()

{

sum = 10;

sumtrig = getent ("sum","targetname");

while(1)
{

sumtrig waittill ("trigger");

iprintln("Your current value is:");
wait (0.1);
iprintln(sum);

}

}

Hello Zelzahim!
In order for "sum" to increase, you need to add somewhere the addition operator to tell "sum" to increase:
sum++; OR sum += 1; OR sum = sum+1;

As for having two triggers to do this, try this script (untested)! I used two trigger_uses with targetnames of "inc" and "dec"

Code:
main()
{
	// Setup the global sum
	level.sum = 10;

	// Thread the inc trigger and dec trigger functions
	incTrig = getEnt("inc", "targetname");
	decTrig = getEnt("dec", "targetname");

	thread trigWatch(incTrig, true); // TRUE -> Set to increase when triggered
	thread trigWatch(decTrig, false); // FALSE -> Set to decrease when triggered
}

trigWatch(trig, inc)
{
	// If the trigger wasn't found, leave the function so we don't get errors.
	if(!isDefined(trig))
		return;

	while(1)
	{
		trig waittill("trigger"); // wait for trigger

		// IF we are set to increase, THEN increase. IF NOT, THEN decrease.
		if(isDefined(inc) && inc == true)
			level.sum++;
		else
			level.sum--;

		iprintln("Your current value is: "+level.sum);
	}
}
nullFew tips for coding.
1. Keep the script as short as possible.
2. Don't comment every line. Only comment portions where they may be needed to point something out.
3. Don't over complicate the script, keep it organized and easy to read.

These help you find simple errors and makes it easy to make changes.

Thanks alot for the quick response. It worked perfectly, thank you!

Also, if you want it to increase 10 each time, how do you do it? It just increases 1.

Just replace the if part with this.

Code:
if(isDefined(inc) && inc == true)
			level.sum += 10;
		else
			level.sum -= 10;
