Asset Creation question

[njohn]

Hi,

I'm trying to understand a bit about asset creation. The following points/questions are based on the "walk" example:

How was the walk_asset.h file created? I.e. what was the exact invocation of gd2asset?
Did you supply 8 separate 32x32 images or a single image with animation frames in it? If so, how to you specify numbers cells/cell size?

Also, what's the use case of the WALK_SHAPE entry?

Thanks in advance.

I used Python scripts for anything more complicated than a single image. So for "walk" the script is:

import Image
import gameduino2 as gd2

class Walk(gd2.prep.AssetBin):

   def addall(self):
       walk = gd2.prep.split(32, 32, Image.open("../assets/walk.png"))[1:]
       self.load_handle("WALK", walk, gd2.ARGB1555)

if __name__ == '__main__':
   Walk().make()

"walk.png" is this:



Regarding WALK_SHAPE, this was a bit of an experiment. Code in Nightstrike uses _SHAPE so it can set up the sprites without having any sizes hard-coded.

If I wanted to get the results of that "split script" in a output asset file instead of a header file, would it be correct to
to set self.asset_file to the file name I want to recieve prior to calling make()?

Thanks, that helps a lot...

I still have problems when trying to mix differnt types of assets with the Cells created by the example above.
Can you expand that script by let´s say adding a sound sample and a jpeg picture in the same asset file, please?
