GZDoom - using animations present in a quake 2 md2 model - need help

[CBM]

GZDoom - using animations present in a quake 2 md2 model:

 

I wish to learn how to use animations present in an md2 file... here is what I have tried so far

 

I have been trying to figure out how to use animations stored in MD2 models

so far, I have read a ton of info online but not gotten any wiser, the examples on the zdoom wiki does not seem to work

I really wanted to be able to use named animations

when I open an md2 model in "misfit" (an md2 model editor and converter), I can see most md2 models seem to use "frame animation" instead of "skeleton" animation... when I use the examples on the ZDoom wiki, then the engine complains that there are no skeleton animations

 

i've been told that in order to make gzdoom use md2 animations, I must use Frame animation.

Amd then know each frame name and what they does.

 

But that doesn't tell me all I need to know, so I hope someone in this forum might be able to help me out.

//and then this..

//the following 4 attempts assume for the sake of easiness, that the model only has an idle animation with 3 frames and then a walk

//new attempt 1

//path, model, skin etc goes here...

//idle - lets just say she has 3 idle frames to make it easy
SDNI A 0 1 // idle animation frame 1 ?
SDNI B 0 2 // 2

//walk - and then lets just say she after that has 3 walk frames to make it easy

SDNW B 0 5  // 2
SDNW C 0 6 // 3

// 6 frames in total - 3 from idle and 3 from walk ?

}

//new attempt 2

//I have yet to try this.... will it work?

model sydney
{

//path, model, skin etc goes here...

//idle - lets just say she has 3 idle frames to make it easy
SDNI A 0 1 // idle animation frame 1 ?
SDNI B 0 2 // 2

//walk - and then lets just say she after that has 3 walk frames to make it easy
SDNW A 1 4 // walk anim frame 1?
SDNW B 1 5  // 2
SDNW C 1 6 // 3

// 6 frames in total - 3 from idle and 3 from walk ?

}

//new attempt 3

//or perhaps this is the way to go???? :

model sydney
{

//path, model, skin etc goes here...

//idle - lets just say she has 3 idle frames to make it easy
SDNI A 0 1 // idle animation frame 1 ?
SDNI B 0 2 // 2
SDNI C 0 3 // 3

//walk - and then lets just say she after that has 3 walk frames to make it easy
SDNW A 1 1 // walk anim frame 1?
SDNW B 1 2  // 2
SDNW C 1 3 // 3

// 6 frames in total - 3 from idle and 3 from walk ?

}

//new attempt 4

//or this???? :

model sydney
{

//path, model, skin etc goes here...

//idle - lets just say she has 3 idle frames to make it easy
SDNI A 0 1 // idle animation frame 1 ?
SDNI B 0 2 // 2

SDNW A 0 1 // walk anim frame 1?
SDNW B 0 2  // 2
SDNW C 0 3 // 3

// 6 frames in total - 3 from idle and 3 from walk ?

}

the model.. sydney..has the following frames

//spawn - 40 frames
//run - 6 frames
//attack - 8 frames
//pain - 12 frames
//jump - 6 frames

//flip - 12 frames
//salute - 11 frames
//taunt - 17 frames
//wave -11 frames
//point - 12 frames

//idle (crstand) - 19 frames
//walk (crwalk) - 6 frames
//crattack - 9 frames
//crpain - 4 frames
//xdeath (crdeath) - 5 frames

//death - 20 frames

16 animations in total

what am I doing wrong?

MD2 models don't have any concept of "animations" stored in them, they are only frames.  So to make an "animation" means to list every single frame number which that animation uses.  The last value of FrameIndex is that frame number, and it begins at zero.

 

If each object is a single MD2 model, then the number before the frame number should always be zero.

 

Each different MD2 model is going to need its own modeldef and its own list of FrameIndex commands to specify the frame numbers.  It sucks to write it all out by hand, but there's probably no tool to help creating these modeldefs.

The best learning tool I can think of is to check out Enjay's Gene-Tech, which is chockfull of MD3 models.

Maverick is the continuation of Misfit.

Also useful is Noesis for checking out the animations.

Yes, I have recently begun to use Maverick and Noesis.

 

I have looked A LOT on projects like Gene-Tech and others that use MD2 and MD3 models in GZDoom... But I just can not make heads or tails around how the modeldef code relates to the actual MD2 or MD3 model

 

for now I have an MD2 model with decorate code that does work, but in order to use other MD2 models, I edit the other MD2 models so they have the same number of animations with the same number of frames as that model I know that works.... it is very far from ideel and often causes the models animations to look ... weird ... in GZDoom....

 

I was hoping that someone might be able to explain in detail how to map sprite lumps in modeldef to actual md2 and md3 model animations (I use Maverick to view and edit MD2 and MD3 animations)

ok, well I had another look at the genetech mod and I think I have finally figured it out

 

I looked at the gunner.md2 model

 

it has 70 stand frames and apparently it means that they must be adressed as "stand00" to "stand69" instead of "stand"

 

not intuitive but atleast now I know :D
