so i was recently following a tutorial for Easter egg radios and i did all the conversions and target names right but when i start m map the all start playing at the same time. and when they end i tried to restart them and once again they all play at the same time. The tutorial was a ZK mapping tut. here is the link t the video and such.

i would have a video of map and such but that would spoil some of the easter egg 

Make sure that you go trough the Tutorial and do all step by step. I think you made a mistake everywhere.

PS: ZKs Tutorial are sometimes a little bit buggy 

If things start without waiting to be triggered in any function it could mean that the ent that says ent waittill("trigger") is undefined. That could throw an error and go to the next step, not waiting. Reasons for this could be misspellings in your kvps, or not making a model a script_model, or something along those lines. In that ZK tut, it looks like, If you get a hintstring and it waits till you trigger it to play, that this isn't your issue. If you get a hand icon though and it doesn't wait to be triggered, it could be.

If you get the hintstring then your ent is good, and since this tut doesn't use getentarray you would get another error if you had multiple triggers with the same targetname kvps, so that prob isn't the issue either. If it activates when you wallk up to the trigger and not when you press use you could have selected the wrong trigger....

Any of this?

Try adding this:

	if(!isdefined(radio))
	{
		iprintln("Error: Radio is not defined!");
		return;
	}

	if(!isdefined(radio_trigger))
	{
		iprintln(Error: radio_trigger is not defined!");
		return;
	}

under the variable declarations. If the game can't find the entities in the map the script will print a message on the screen and return the function.

thanks that fixed it
