i stumble across this every step of the way and i m tired of using different long workarounds witch add to much code.
in a step event how can i trigger something only oance?or not necesarly only step event, in general i need to trigger something only oance.but i need to trigger it again some time later.for example if X>y do this... then stop, the code will eventualy build enaugh units so that x<y but i need the code to run again(only oance again) in the future when and if x >y again,

Something like this?

//The event where you allow the trigger
trigger_alowed=true

//Step event example
if (trigger_alowed==true) then {/*Do stuff here*/ ; trigger_alowed=false}

yes that s the ideea but won"t the first event just trigger the second command again?
And if the first event is in a step event it will just trigger it over and over again

for example.P-number of needet people.and I number of inhabitants allowed.
If P>I ds queue add( build,(P-I)/4).meaning that for evry one person i need a house
but it will add the number to the queue evry step...witch is a mess
i need it to add 4 to the queue just oance until P<I .then run it again if in the future P>I but again only exactly oance.
Did i make any sence?

Nono - not if the variable is set to 1 only once, for instance when you press a button or in a create event.

//Create
var_happen = 1

//Step
if var_happen = 1
{
    //do stuff
    var_happen = 0
}

No, ihato's code will only run the "do stuff" coding once during that trigger event.

No, in a step event if nothing meets the qualifications of the "checks" or coding that is not run after a check, then the only thing that happens is that the checks are run and return values, IF THE VALUE IS NOT MET TO TRIGGER A CODE STRING THEN NOTHING ELSE HAPPENS. Sorry for the bold I am just using it to overemphasis what happens in a step event.

for example.P-number of needet people.and I number of inhabitants allowed.
If P>I ds queue add( build,(P-I)/4).meaning that for evry one person i need a house
but it will add the number to the queue evry step...witch is a mess
i need it to add 4 to the queue just oance until P<I .then run it again if in the future P>I but again only exactly oance.

if p>i //so only if p is greater than i;
{ds_queue_add(build,(p-i)/4)} // then do this stuff

Seems pretty straight forward. In that example you only do the following code when p>i, so the only time that would constantly run is IF p is always greater than i. This however is not good because until p<=i this will happen every split-second (depending on game speed) until the governing "if statement" returns a value "other than" the requisite. In the case of what I am guessing you want happen YOU HAVE TO USE A VARIABLE THAT YOU REFERENCE AS A TRIGGER AND THEN SET IT BACK AND FORTH FROM 1 TO 0 and then either set an alarm up, or code in a timer (if you know how, otherwise use an alarm) to set the variable back when you want to be able to perform the action again.

Wow. That could be too much or not well explained. I hope that helps.

so something like this,
in create event c=0
then in step event
if c=1
{
if P>I
{ds_queue_add(build,(p-i0/4)
c=0
}
}

but where do i make c=1 again for when p.i again>?

Well you could set a timer or alarm to reset the variable after a set amount of time. Or there could be an event that resets it. Kinda one of those things you got to figure out yourself, because each game is vastly different and each circumstance is unique and needs to be handled according to the rules and laws of logic. So in this instance, I will assume it is an TBS or RTS where you build structures. So what I would do is, when you click to build something reset the variable "c" to 1. If my assumption is wrong just find a trigger point in your game. It's a lack of details that is preventing me from helping you fully right now.

[rdt]

thank you, i just have to find a trigger point then.you;re right it is a rts game but i'm making a self taking care ai, so no clicks on buildings or chosing what to do, he does that.and it s getting more complicated each step because of adding a lot of variables that need to be triggerd each and there just to take out different small problems

[XxTaLoNxX]

Ah so I see. What algorithm are you using for the AI to "decide" what to build? Can you insert the variable trigger into it?

Extremely rough example...

if something happens
{queue_add=building 1{c=1;}}

For now I'm at the need part of the ai, the surviving part,it needs to feed itself because each worker it has consumes some food every minute,so rough description of it, of what i ve done so far is that it creates seekers, witch go around the world, until they find the needet resource, mark it s position, return to base then send gatherers to gather from that resource.and if there s no food need it will chose randomly betwen a list of priorities, i just need to get a algorithm witch will add just a little more chance of being chosen to some of the things on that list.
or if someone else has a better ideea please do tell, maybe it will give me a ideea, this is my first game and first time programing, i dont know if there are specific routes to follow and so on, i just have ideeas and put it in practice with what i know:P

[rdt]

will trigger events that are called in a step event be triggered only oance?
also will trigger events that are called in a alarm be triggered each time the alarms sets off?if it s a looping alarm
