An idea about rotating npcs

Adam3 · Post by **Adam3** » Mon Jan 15, 2007 6:12 pm

I was just wondering, is it possible in zdoom to make a npc kind of rotate when it is blown into the air? you know kind of like if you fall off a cliff you would lose control and spin and twist about?
Is that possible?

Sure, you just have to draw the needed sprites for this

Well I could try that(if I knew how)
but what Iam talking about is ingame sprite manipulation and morphing ,like turning something upside down with the doom engine.
Either that would take A lot of ACS or a heavily modified source code,I mean if zdoom can make slopes,Im sure it could set an imp flying out of control yet smoothly without the use of extra animation frames.

ZDoom can’t flip images for some reason, and I'm sure nothing is going to be done to change that

The Doom engine is not capable of rotating images, which is what would be required for this to work.

The reason is quite simple -- it uses a column renderer to do pretty much everything, and when you start rotating images, that renderer no longer works.

oh well...how about duke nukem 3d?

Duke3d can't do it either, or 1/4 the stuff you could do with ZDooM.

Hmm... I guess only 3d models instead of 2d shapes would work in Fps...
ok then, how about zdoomgl and its 3d models?

The last time I checked, ZDoomGL didn't have model support (And no, I don't count the one ZanZan was intended for since the feature was removed since.)

You could try your luck with GZdoom models though.

Well,that might work...although the only experiance
I have with doom editing is textures and a little mapping skill
(If I spend the hours intended hehe..)

Not true. Play through Action Doom on hard and kill the final boss. He rotates as he flies into space.

that was simply achieved by drawing different sprites for each frame of the rotation.

He's got extra sprites for that though, look in the wad.

I can't quite figure out exactly what this thread's about, but oh well.

That is exactly my point.
