Entity-spawning limitations?

[vinny]

I've been working on a small mod that allows you to play as an engineer, which can build structures during the game. Not turrets, like in TF, but buildings... something like an RTS mix. Is this possible in the id Tech engine?

@vinny: There is only one game currently supporting that: Minecraft

You want to make a mod that will be alike a Minecraft? I think it'd be impossible with only a mod, that may require engine changes and this requires standalone game. Thus you will be unable to use original Quake 3 assets as they are copyrighted by id Software.

Also why you need to copy idea of already existing game? Try to pick source code of Minecraft and try to make higher quality textures for it

pretty sure he doesnt mean build buildings from scratch. he means plopping down buildings for resources, similar to how an RTS works. Or the game C&C Renegade in multiplayer.

[vinny]

No, not Minecraft. I don't want players to create or design buildings, just spawn prefabs. Something like this: https://www.youtube.com/watch?v=guOQtzeFvYA

I'm just curious about how to handle this in code: is it possible to spawn BSP prefabs on top of my level? Or i can just spawn MD3 models? What about lighting?

ps.: If someone reading this is actually looking for Minecraft-ish behavior, Minetest would be a good alternative.

MD3 models are certainly possible, but they won't be lit with lightmaps and they're non-solid, so you'll have to come up with some solution for that.

[D-Meat]

... and they're non-solid

Or actually, you can only have collisions boxes (I don't even know if the collision boxes can be rotated ?)

[vinny]

Don't MD3 have collision set automatically?

[Eraser]

Definitely not. In-game entities work with collision boxes and md3 geometry (part of the level) needs to be clipped off with (invisible) clip brushes in Radiant.
