How does it do it ?
I don't see any behavior attached to the trigger zone, they just play sounds "PIrinzone ?", did I miss a small trigger space ?
I clicked the "Shooter Games" button to see if there are any "connecting lines" that triggers it via some mysterious trigger zone, but I don't see anything, how was it done ?

And also on the left side...after the objects are there in the library...I cannot right click and delete, so how do you delete it ?
Thanks.

Ok I am seeing "Plays SOUND0 when player enters the zone and activates any objects set in the ID USED property. Removes the zone afterwards so should be used to trigger an event or play a one time only sound."

I go to another location, that's where I see the trigger, but all I see is a textbox with a description of the trigger and sound0 where I get to select the sound.
Where do I set the ID USED property ?

When you drag the Trigger Zone into your scene, it should have a Behavior. If you look to the right-side, under Object Tools, you should see a Behavior twirl-down panel. If you twirl that down, you should see the Plrinzone (Player In Zone) Behavior attached. Under that, it has Sound0. The change that sound, click the three "..." at the end. This will bring up the Music and Sound Library, allowing you to either choose one of the supplied sounds/music or to import your own.

Awesome, yes, see that it allows you to play a sound of choice, may I know about the "activates any objects set in the ID USED property".
I think that was the way the metallic cage appear in that game when you enter the zone. but I have no idea how it was done...how do you set the ID Used as mentioned in the behavior ?

And also, your keep up the good work on your tutorial videos !

After putting your trigger zone in your level, you would click on the Shooter Game icon. Then you could drag a connection to another object to "trigger it" once the player steps into the trigger zone. Clicking the sphere on the connector gives you options as to how that trigger works. What those options are will depend on what you connect to (for example, they would be different if you connected to a character as opposed to connecting to a light).

Also - thanks on your kinds words concerning my videos.

Actually i did it the old fashioned way by just typing in the name of the asset in the " Ifused " field
The sound is also part of the triggerzone which is the crash of the bars and the laugh all in one sample.
I never over complicate my ideas

Arh I see synchromesh !
I was wondering how to activate the "Developer Settings", thank you

I am honored to be talking to the guy who made that level ! It scared the bejesus out of me !

May I trouble you with two more questions ?
1: By typing "CAGE" I am able to make it appear, cool.
How do I change the name/identifier of that object in the GUI ?
In case I have multiple cage everywhere and I only want the trigger to make this particular/a specific cage appear.

2: Is there a script that make the cage appear when you enter the trigger and when you do it again, it disappear and you enter again and it re-appear, and you enter again and it disappear ? I think you get the point.

1- Just place another cage and rename it as CAGE2 .. etc
When you click on each they will have different names the Ifused can use.

2- Not by default that i am aware of but you could probably adapt one.

Thank you synchromesh.

I do wish people would bother to read the manuals or tutorials

Heh. Yeah, that would help ... a lot.
