global vars

hi

if i define global var like:

A=4;
default
{
etc.

i cant change its value in the script???

i made that:

integer Counter=1;

default
{
state_entry()
{

}

control(key id, integer down, integer new)
{

if (pressed & CONTROL_UP & LineCounter>1)
{
state PGUP;
}
if (pressed & CONTROL_DOWN & LineCounter<7)
{
state PGDN;
}
}
}

state PGUP
{
state_entry()
{
LineCounter-=1;
state default;
}
}

state PGDN
{
state_entry()
{
LineCounter+=1;
state default;
}
}

whats wrong with that???
and how can i do that?

Counter or LineCounter?

oups !!
all the linecounter are actually counter... i forgot to change them... i copy paste it from SL....

if (pressed & CONTROL_UP & LineCounter>1)
{
    state PGUP;
}
if (pressed & CONTROL_DOWN & LineCounter<7) 
{
    state PGDN;
}

I think these if statements aren't quite right.

If you want to say "if (this is true and that is true)" then you should use &&.

If you want to test for certain bits being set then you should use &.

I think you want:

if ((pressed & CONTROL_UP) && LineCounter>1)
{
    state PGUP;
}
if ((pressed & CONTROL_DOWN) && LineCounter<7) 
{
    state PGDN;
}

Meade is correct, & is numeric/bitwise and, && is logical.
(I hadn't even looked that far after seeing the mismatched variable names.)
