|
|||
|
|
|
|||
|
|

|
|||
|
|
|
|||
|

if(condition,valtrue,valfalse)
|
|||
|
|
= returns 'valtrue' if 'condition' is nonzero, returns 'valfalse' otherwise.
|
|||
|
|
new in AVS 2.8+: only one of valtrue/valfalse is evaluated, depending on condition
|
|||
|
|
|
|||
|
|
assign(dest, source)
|
|||
|
|
= if 'dest' is a variable, assigns the value of 'source' to it. returns the value of 'source'.
|
|||
|
|
a little trick: assign(if(v,a,b),1.0); is like if V is true, a=1.0, otherwise b=1.0. :)
|
|||
|
|
|
|||
|
|
exec2(parm1, parm2)

|||
|
|
|
|||
|
|
exec3(parm1, parm2, parm3)
|
|||
|
|
= evaluates parm1, then parm2, parm3, and returns the value of parm3.
|
|||
|
|
|
|||
|
|
equal(value,value2)
|
|||
|
|
= returns 1.0 if 'value' is equal to 'value2', otherwise returns 0.0
|
|||
|
|
|
|||
|
|
above(value,value2)
|
|||
|
|
= returns 1.0 if 'value' is greater than 'value2', otherwise returns 0.0
|
|||
|
|
|
|||
|
|
below(value,value2)
|
|||
|
|
= returns 1.0 if 'value' is less than 'value2', otherwise returns 0.0
|
|||
|
|
|
|||
|
|
megabuf(index)
|
|||
|
|
= can be used to get or set an item from the 1 million item temp buffer
|
|||
|
|
to get, use: val=megabuf(index);
|
|||
|
|
to set, use: assign(megabuf(index),val);
|
|||
|
|
|
|||
|
|
loop(count, statement)
|
|||
|
|
= executes <statement> <count> times. count is evaluated once and clamped
|
|||
|
|
to 0..4096. best used with exec2() and exec3() and assign(). Note that
|
|||
|
|
the return value of loop() is undefined and should not be used.
