ANIM_3D_TRANS Blender Export possible - python

[astorian]

Hello to all WZ fans, contributors and especially development team.
I was helping some people creating/exporting animations from Blender to a game project. The game used models with animations in game engine - calling separate animation file that contained the rotation/movement parameters for set of objects.
So i remembered the time i spend to work on WZ2100 and i realized the same thing of animation could be used for WZ.
I am talking about work that can be actually done in the current state of the WZ2100 project without code change.

The ANIM_3D_TRANS type of animating models in WZ makes it possible. HOW?
The ani file contains the rotation/movement/scaling coordinates for each objects center that is contained in the animation pie file. A good example is the oil-rig file:

/* header format: anim3d [filename] [frames][framerate] [num objects] */
/* anim line: [frame] [x] [y] [z] [xrot] [yrot] [zrot][xscale] [yscale] [zscale] */

The power of this animation type is that the game only loads the models (3 in this case: DerrickBase, Piston and Box03) and uses the coordinates to move,rotate and scale them. So you are able to do smooth animations using small amount of resources with just adding more "action" lines to the ani file.
(The frame animation has to load all models in each frame, so a smooth animation would consume lots of resources to preload all frames. And you would have to create lots of frames to make the animation smooth.)

I know what you think: Manually adding lines to the ANIM_3D_TRANS ani file takes huge amount of time. Therefore the whole idea is based on the automation of the animation process using blender's exporter. So you create a pie file for the static object and then animate them in blender (walk cycle for example) and then export an .ani file like the one above used for oil derrick.
Therefore i am looking for Python coders to help me create a python export script for blender, that creates a ani file - export coordinates and rotation to a text file. Its nothing new, those export scripts exists already, but i lack script skill to do that.
If there is a WZ fan or artist that understand python scripting and willing to help, plz let us know!

The problem is that only the oil derrick can be animated using ANIM_3D_TRANS. :-S

Well that is not true, i successfully tested ANIM_3D_TRANS animations on cyborgs pie files and on custom objects.
Its just the ani file that decides what type of animation is used.
I used a custom model of a wheel for instead of cyborg and animated the rotation. It was simple since there was only one z axis coordinate and i used y axis rotation to spin the wheel. Worked without problems.

Can you post the script?

[astorian]

Can you post the script?

You mean a python script for blender exporting cordinates? Or the custom ini for the cyborg i made?

maybe both, but I would be interested in the pie ans ani files^^

Hi i will make new ones in few days and post them here so you can try them out.
