Func_illusionary Created 20 years ago2004-06-12 03:35:10 UTC by AJ

Sorry for all this posting btw...

Do you remember at the start of Half-Life in the transit, there was a machine holding a crate. The door opened and the light started to shine through. It looked like a func_illusionary to me. I was wondering if anyone knew how to achieve the effect, to have the light showing matching the amount of door opened (if that makes sense!).

I get what you mean. It's quite simple actually. That light-beam is just a moving entitie with it's render FX set to additive. It moves so that it fits the amount of door opened. It would take a bit of tweaking to get it right but it's fairly simple to achieve.

Ouch it actually sounds quite difficult. I know about the Render FX part. I've set up the actual light which is supposed to come through an open window. The window is covered by two shutters. These shutters swing open and start to let light in until they are completly open. This was my idea anyway...

In the intro-ride, the door slides open and another door, the lightbeam, slides forwards, so, that it exactly fits each other. Effectively simulating the light...

It's not so easy in every situation though. With rotating doors and doors that open on two sides the light is a lot harder to get right...

Ah I see...That would be quite difficult for a set of shutters...Perhaps two lightbeams are needed.

Probably. Maybe an even more advanced setup. That's up to you to find out... always fun, mapping, isn't it?

you could bust open the windows really fast - then you can use a func_wall_toggle

BTW I'm mapping for Spirit if that helps...

(is it posible to make it fucn_illsionary then group it with the door so it moves with it)

With Spirit of Half-Life, yes. With Half-Life, no. Although a lot can be faked with a little creativity...

Well anonymous, if you have any luck contact me. I'm quite interested at having a look if you get it done.

It's still solid if it moves though, right? It looks transparent due to the additive, but if it's a func_door or train or whatever, it's still solid.

Nope, just tick the 'Not Solid' flag.

Hmm...I see no "not solid" flag on a func_door in VHE 3.5. Anyways, I'm posting an example map of how to do this, with non-accessable doors (solid) in the example maps for future reference.

A func_train has the 'Not Solid' flag.

Ah. I've been working with it as a func_door as it is so much easier. I hate path corners.
