@Nick: I'm not sure how xpos and zpos effects platform but one thing for sure, it should be same with offset.
anim idle
delay 100
offset 12 37
platform 12 37 0 0 50 50 10 10

I have tried altering xpos and zpos and the platform become altered too
. I have no clue what happened so I just make it clear that xpos and zpos should be same with x and y offset respectively for easy reference.
Oh it has nothing to do with z coordinate AFAIK.
Come to think of it, since the platform is invisible, any offset value will do.
alt (last number); why would I set an alt in the platform, when I could just spawn it in the level with the y/a coord I want?
It should be height. Altitude defines the height of platform. This plat03 platform is short only 10 pixels height. If set high, you can make wall with platform.
As for confusing, I believe that's because of platformizing (placing invisible platforms to platformize/make platforms in background solid/real). It's confusing cause you really need good imagination. Plat03 in the Blank2D mod is used to platformize the platforms in Battle levels. Without it, the platform will only be decorations.
If you're still new in 2D platform, I suggest studying platform work in Vertical level in the mod. The platforms are visible there so you can see if you do it right or not.
@Vycks: I'm downloading the demo now. I'll give it a try later.
