ZDoom

A much simpler solution, using ACS, decorate and 3d models. It doesn't carry players while it's extending, but it does once it's fully deployed.

I would create models in ultimate doom builder. A whole wall, then a damaged wall, and use the models as frames in decorate/zscript. I've been thinking about destructible columns, to eventually bring the ceiling down on monsters (or on you, as a trap). Imagine your cover gets destroyed by a well ...

Let me start at step 1 - what modeler program should I use? Blender? I just want to create a cube, so don't need anything fancy. If I could create a model by hand in a text file I'd be fine with that. If a cube is all you need, you can use ultimate Doom builder and export it as obj, then import the ...

You could use an actor as your wall.

Quake Style Secret Door

So, it's:
Script 1 (void)
for(int i=0; i<64; i++)
{
//Do code here
}

I need a loop, but my knowledge is limited. I need to move an actor in one unit increments, and writing the same line 64 times seems too much.
Maybe someone knows how to do it, or can point me to a tutorial. The examples in the wiki don't help.

Thanks.

As promised, here's the map. Just a few rooms and no monsters. Sorry about the sounds. They were picked in a hurry. If you know how to create models in Ultimate Doom Builder, this will be a piece of cake. Maybe someone with more experience could simplify the scripts, or even make interactive ...

Apologies.

It seems the pk3 I uploaded has an extra decorate file that needs to be removed.

I'm sorry.



I'm preparing a sample map with everything I have:

Door

Bridge

Chest

Lever

Valve

Yes, they can. Set the line flags to "block everything" and "monster activates" and the activation to "repeatable action", "when player presses use" and "when monster bumps".

I tried and they open the door, but find it hard to go through.

Once you figure it out, you'll see how easy it is. There are 2 scripts: Swing Bump One for each side of the door. And there's 2 lines ...

Thanks

These tutorials helped me a lot, and continue to do so.

Keep up the good work.
