How can you make a player, soldier or whatever, look semi transparent, white with no features, like a ghost? Yet he still walks around of course.

you could just give a normal model a white texture and set his transparent flag on.

Add this to your entity's action:

my.transparent = on; // make entity transparent
my.alpha = 60; // play with this number - 60 means 60% or 153

Thanks for the answers. Sounds easy. I thought it would be neat to do a game with all the models looking like white ghostlike sillouettes. Tired of the included models everyone sees and not smart enough to make humans who have the animations. If I see that pink haired b***h one more time I'll scream.
Just kidding.

I second that commment on the CBabe. Shes embarassing, and even when some users try to "improve" her, she still looks like a smash-faced abomination. Dont get me started on her animations.
