What expression?

What expression would I put into a sprite if I wanted it to lose some width everytime the player got hit

you could use

set width | self.Width - 'value'

value is the amount you wish to deduct from the width of sprite

for some reason, when I put minus it counts as a syntax error

Try looking at this.

Might not be the best ways to do it , but might help a little.

PowerBars.capx

If you want to make a health bar (or power bar) you can try:

HealthBar.width=(Self.InitialWidth + (Player.Health-PlayerMaxHealth)*(Self.InitialWidth/PlayerMaxHealth))

InitialWidth = instance variable

Change color:

You could use setcolor effect:

with function you can set color

*compare player.health > 66/100*playerMaxHealth then set color "green"

playerHealth is between 66/100*playerMaxHealth and playerMaxHealth*33/100 then set color "yellow"

playerHealth <33/100*playerMaxHealth then set color "red"

If you want to have your life bar gradually change color, do this :

Add a "SetColor" effect on your bar and set these defaults values :

Red 0

Green 100

Blue 0

Then do this :
