why won't this work?

+ Code Snippet

ammo = 2000

TEXT 0,SCREEN HEIGHT()-50,"Ammo: "+str$(ammo)

do
 if mouseclick()=1
   if ammo>0 then dec ammo,1
 endif

sync
loop

i want ammo to be decreased by 1 when you click the mouse button and it show the number gradually decreasing on the bottom of the screen, but it's not doing anything. Why is that?

Krimzon DestinE,

The decrementation code works fine. However, the text is not being retyped to the screen at all. Try this.

+ Code Snippet

ammo = 2000

TEXT 0,SCREEN HEIGHT()-50,"Ammo: "+str$(ammo)

do
 if mouseclick()=1
   if ammo>0 then dec ammo,1
   cls
   TEXT 0,SCREEN HEIGHT()-50,"Ammo: "+str$(ammo)
 endif

sync
loop
