While answering a question on another board an idea came to mind on how to ghost a limb. The method is this:

[EDIT] I've changed the method a bit -

1. Create or load 2 of the same object with limbs
2. Consider object 1 the main object (to have ghosted limbs)
and object 2 as the "ghost enabler" so to speak
3. Position and animate the objects in the same place and speed
4. For the limb that you want ghosted of object 1, hide the limb of object 2
5. Ghost object 1 on.

That should do it!

Here's an example:

rem ghost limb
rem by latch
rem 3/9/2008

set display mode 800,600,32
sync on
sync rate 60
autocam off
hide mouse

rem put down a matrix for reference
make matrix 1,1000,1000,20,20
position matrix 1,-500,-200,0

gosub _characters
color backdrop rgb(100,100,100)
position camera 0,-60,-200

rem ghost one of the legs
   rem hide the limb in object 2 that you want to be ghosted in object 1
   hide limb 2,2

rem now ghost the outside object entirely
   ghost object on 1

sync

wait key

end

rem make an object with limbs
   _characters:
      rem textures
      ink 255,0
      dot 0,0
      get image 1,0,0,1,1
      sync

rem main character
      make object sphere 1,25
      make mesh from object 1,1
      make object box 2,5,30,6
      offset limb 2,0,0,-15,0
      make mesh from object 2,2
      delete object 2
      add limb 1,1,2
      add limb 1,2,2
      add limb 1,3,1
      offset limb 1,1,-6,-6,0
      offset limb 1,2,6,-6,0
      texture object 1,1
      hide limb 1,0

rem animate
      set object keyframe 1,0
      rotate limb 1,1,30,0,0
      rotate limb 1,2,330,0,0
      offset limb 1,3,0,-5,0
      set object keyframe 1,10
      rotate limb 1,1,0,0,0
      rotate limb 1,2,0,0,0
      offset limb 1,3,0,0,0
      set object keyframe 1,20
      rotate limb 1,1,330,0,0
      rotate limb 1,2,30,0,0

      rotate limb 1,2,1,0,0
      offset limb 1,3,0,-.5,0
      set object keyframe 1,38

scale object 1,400,400,400

loop object 1
      `hide object 1

rem ghost
      make object sphere 2,25
      add limb 2,1,2
      add limb 2,2,2
      add limb 2,3,1
      delete mesh 1
      delete mesh 2
      offset limb 2,1,-6,-6,0
      offset limb 2,2,6,-6,0
      texture object 2,1
      hide limb 2,0
      `hide object 2

rem animate
      set object keyframe 2,0
      rotate limb 2,1,30,0,0
      rotate limb 2,2,330,0,0

      rotate limb 2,2,1,0,0
      offset limb 2,3,0,-.5,0

That`s a great idea. Latch! although, it`s going to slow down the game rapidly.

So, you said position and animate both objects at the same place and speed. Object 1 is ghosted, object 2 isn`t. You hide the limb from object 2 that you want ghosted. But you forgot to hide the limb from object 1 you don`t want ghosted.

Anyway, that`s a great method and thanks for helping me out.

It may depending on the number of objects displayed at once that need ghosted limbs.

Quote: "But you forgot to hide the limb from object 1 you don`t want ghosted."

I thought about that... And maybe it would help with performance if you had many objects displayed at the same time that you wanted ghosted limbs, I haven't run any benchmarks so I don't know how much of an improvement on speed there would be. For management sake, I left it out because if you had a 50 limb object you wanted to ghost one limb on, you'd have to hide 49 of the limbs you didn't want ghosted, then show them when ghosting was off; and on the flip, when you didn't ghost a limb, you could hide object 2. I just wanted to get to the point of ghosting the limb. The feasibility of hiding everything not ghosted really would depend on the performance increase. Run some tests, see what works best.

I don't doubt there are a lot of optimizations that can be made on this. Like if you know you'll only ever ghost the visor of a helmet, you might just have a visor object glued to the helmet and ghost that.

Enjoy your day.
