Hi, may some one give a helping hand on how to create a KOF(king of figther)/warcraft like life bar?

A rectangular, with another rectangular inside and is filled, which can reduce the width when the life reduced

Thanks

You'll need two images, one for what it looks like when your lifebar is full and one for when it's empty. If it's a Gui, create a GuiBitmapCtrl named LifeBarEmpty and set its bitmap property to the empty bitmap file at the full extent of the life bar. Then create a child GuiBitmapCtrl called LifeBarCurrent and initialize its extent to the same thing. When the player's life goes up or down, set the extent of LifeBarCurrent based on the ratio:
(currentLife / totalLife == extentTicks / totalTicks)
extentTicks = currentLife * totalTicks / totalLife

So you could use:
LifeBarCurrent.extent = (currentLife * getWord (LifeBarEmpty.extent, 0) / totalLife) SPC getWord (LifeBarCurrent.extent, 1)

For example if you have between 0 and 100 life and your life bar is 250 pixels wide, each hit point is worth 2.5 pixels. If they take 2hp damage, the new extent of LifeBarCurrent is 98 * 250 / 100 == 245.

Works the same with sprites using t2dStaticSprites and the size property instead of extent.
