Limitations of the compiler
1. You cannot use nested foreaches it will cause an infinite loop
2. You cannot use continues in foreaches or for loops it will cause an infinite loop
3. You should always use parenthesis when comparing values using conditions while using operators
( 0 - 1 ) < 1 is NOT the same as 0 - 1 < 1 the compiler will compile it as 0 - ( 1 < 1 )
( 0 - 1 ) < 1 will return 1 because 1 is greater than -1
0 - 1 < 1 will return 0 because it will compare the values then subtract
ALWAYS SPECIFY PARENTHESIS WHEN OPERATORS ARE INVOLVED
4. You cannot use more than 2 conditions in an IF statement connected by OR operators enclosed in parenthesis EXAMPLE:
if ( ( a || b || c ) && d )
WILL NOT COMPILE
However, you can rewrite this as:
if ( ( a || b ) && d || c && d )
OR
if ( a && d || b && d || c && d )
5. You cannot use OR operators in an IF statement in parenthesis if the string of conditions would not be on the leftmost side of the if statement and the number of conditions on the rightmost side is not at least 2. EXAMPLE:
if ( a && ( b || c ) )
WILL NOT COMPILE
However,
if ( ( b || c ) && a )
WILL COMPILE
In the case of
if ( ( a || b ) && ( c || d ) )
WILL COMPILE
6. You cannot set variables equal to a condition
EXAMPLE:
a = b && c;
WILL NOT COMPILE
7. Scripts that contain #using_animtree( "animtree" ); will compile but crash upon loading Unfortunately, for certain scripts #using_animtree( "animtree" ); is required for the script to function so scripts containing it will crash on start/while running There is a workaround using script names such as maps/mp/gametypes_zm/_globalentities and naming an extracted but not decompiled script
8. You cannot use variable defined notifies/waittills with extra inputs/outputs
EXAMPLE:
var = "connected";
level notify( var, player );
level waittill( var, player );
WILL COMPILE BUT
The notify/waittill won't work.
9. Ternary op compiles but doesn't work as expected
Instead of returning one of the two values specified the compiler will compile it to return bools instead.
