I've been playing around a little with Shrodinger's absolutely brillo P3D engine (if you haven't checked it out, you totally should).
I'm not really trying to make a full on game or anything, just trying to see what's possible. And since I've decided that 2016 is the year I'll actually engage with these forums, I'm making a little post about this so y'all can see what I'm up to.
Right now, it's pretty simple:
Using P3D to render the world and enemies.
Loads and constructs the level from array files saved from a level editor
There is line of sight for the player to shoot,
Line of sight for the enemies detectin the player
A (simple,but expandable) state-engine for the enemy AI (currently has idle and shoot)
Some little screen effects.
My main interest is whether P3D can be used to make a simple Wolfenstein clone
Still to do:
Add some decent path-finding and combat AI
Exploration mechanics like door/keys, switch/keys, and secret areas
Add level exits and load multiple levels.
I also need to port the game to the latest P3D (I'm using the beta and there's a change in the release version that will greatly improve performance)
When I'm done, I'll upload this as some kind of tutorial for other people interested in doing doom style games.
Anyway, that's it for now. Happy new years!
EDIT: Credit where it's due - I'm using sprites from Operation BodyCount, which is a really old FPS from the DOS era, the walls are mine tho
