Wait_Until Question

vegastech

I have a wait_until placed in each of my source functions, but it seems that the wait_until only triggers when the system was previously off, not while it is on:

DEFINE_FUNCTION fcnDVD()
{
	IF (nPower = 0)  //Room Off
	{
		//turn room on, set waits/timelines, etc
		fcnPwrOn()
		
	}
	
	
	WAIT_UNTIL(!TIMELINE_ACTIVE(tl_ProjWarmUp))
	{
		SEND_STRING dvPROJ, "cProjComp,fcnCheckSum(cProjComp)"  //proj component input
		nCurrentSource=1
	}
	
}

My hope here was that the wait_until would work as a sort of flag when the system is already on. Am I just coding this wrong, or do I need a different flag to check other than the active/inactive timeline? I figured the timeline was good because it has the necessary 45 sec. delay aready in it.

I'm not sure that there is anything wrong with what you are doing, but personally I would just create a ProjectorReady variable and set it to 1 when the warmup time is done and set it to 0 when powered off. Then you could do a wait_until(ProjectorReady).

This would also be easier to track in debug for troubleshooting purposes.

Figured it out...Wasn't the previously posted code. It was here in my button event:

BUTTON_EVENT[dcSources]  //latches source buttons together
{
	PUSH:
	{
		nCurrentSource = GET_LAST(dcSources)
		IF (nPower = 0)  //<----------------------------------Sneaky!!!!  
		{
			//start the projector polling, send proj pwr, update var text fields
		SWITCH(GET_LAST(dcSources))
		{
			CASE 1: fcnDVD()
			CASE 2: fcnCamera()
			CASE 3: fcnSAT()
			
		}
		}
	}
}

Switch-Case doesn't exactly work here if the room is already on....Guess that's why I should really proofread my code as I do revisions!
