|
|
= returns the greatest of 'value' and 'value2'
|
|
|
|

|
|
|
|

|
|
= returns a random integer between 0 and 'value'
|
|
|
|
"band(value,value2)
|
|
= returns a boolean AND of 'value' and 'value2'
|
|
|
|
"bor(value,value2)
|
|

|
|
|
|
"bnot(value)
|
|
= returns a boolean NOT of 'value'
|
|
|
|
"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)

|
(start_time can be -1.0 for current play time in seconds
|
|
(start_time can be -2.0 for current play length in seconds
|

loop(count, statement)
|
|
= executes <statement> <count> times. count is evaluated once and clamped
