Map Boundaries...

by Derrick Austin · in Technical Issues · 11/10/2007 (11:48 am) · 10 replies

I am using this code to "warp" across the map in a circle kinda effect, how could I modify this to instead have the player hit a invisible wall kinda deal?

function GameConnection::onLeaveMissionArea(%this)
{
	%longitude = getword(MissionArea.Area, 0);
	%latitude = getword(MissionArea.Area, 1);
	%width = getword(MissionArea.Area, 2);
	%height = getword(MissionArea.Area, 3);

	%tf = %this.player.getTransform();
	%x = getword(%tf,0);
	%y = getword(%tf,1);
	%rotation = getwords(%tf,3,6);
	
	if(%x < %longitude){
		%x += %width;
	}else if(%x > (%longitude+%width)){
		%x -= %width;
	}
	
	if(%x < %latitude){
		%y += %height;
	}else if(%x > (%latitude+%height)){
		%y -= %height;
	}
	
	%found = ContainerRayCast(%x SPC "1000", %x SPC %y SPC "-1000", $TypeMasks::TerrainObjectType, %this.player);
	%newPosition = getwords(%found,1,3);
	%this.player.setTransform(%newPosition SPC %rotation);
}

You mean like repeating terrain? If so, a repeating map is the default kind of map in Torque.

No, instead of repeating just like an invisible wall at the edges...

You could create an invisable .dts file, and change it's scale untill it fits the edge of the map. Just make sure it has a collision mesh on it.


You got 3d Game Programming All In One, didn't you? Awsome book.

Thanks Nathan, I was thinking of something like that but I didn't think of the scale deal and I REALLY didnt want to walk all around the map putting down "fences" lol.

Yup, great book. The above code is actually from "Advanced 3d Game Programming All In One" though ;) lol, its just about the same just a little more in depth on stuff missed in the first book. Check it out if you haven't!

Just starting to get this game engine figured out, having fun though. I lack a lot in the graphics/design/creativity side of things, but I consider myself a pretty good programmer so we'll see how it turns out. If nothing else, I'm getting some valuable experience! lol

Ok, here is the current problem.

I made a box with no texture file and with a collision mesh.

I load inside the box, and I don't see the box (Which is good.)

I can leave the box and then I can see the box (Bad)

I can't get back inside the box (Good that collision works on one side, but I shouldn't be able to leave in the first place...)

Any ideas?

BTW, that is milkshape 3d.

I can get the walls to work by building the box a different way. Instead of a box then cutting off the top & bottom I made four sides and that works, but I still have a blue texture on it... If I could make it invisible I'd be a happy camper! :)

Ok, update:

I used a transparent png as the texture and in milkshape the box is invisible. In the game, however, the box is now gray on 3 sides and white on the other.

WOHOOO!!! Ok, for future readers:

1. You must make a box out of planes, basically an inside out box, or else you can escape.
2. I used a transparent png as the texture for the box.
3. When exporting from milkshape, click on the material name, then the edit button. This brings up a new screen. Underneath "Flags" check the translucent box.

Thanks for your help everyone!

Also, you can choose to export the object as a collision mesh. It won't be visible.

Oh, actually I forgot that step ^^


In order to make the box where you can't walk right through it you have to regroup the box, then rename the group: collision-1.


It is still visible if that's all you do though.
