Many AVS effects allow you to write simple expressions to control
|
||
|
|
visualization. Here is a brief summary of how to write AVS code.
|
||
|
|
|
||
|
|
Many aspects of AVS code are similar to C (including comments).
|
||
|
|
|
||
|
|
You can create new variables just by using them, and you can read
|
||
|
|
and write predefined variables (of which each effect has its own)
|
||
|
|
to interact with the effect. Note that variables are all floating
|
||
|
|
point numbers (no strings), and the maximum length of a variable's
|
||
|
|
name is 8 characters (anything longer will be ignored.
|
||
|
|
|
||
|
|
So, to create a variable, you can simply use it, for example:
|
||
|
|
x = 5;
|
||
|
|
|
||
|
|
You can also use a variety of operators and math functions to
|
||
|
|
modify variables, see the Operators and Functions tabs above.
|
||
|
|
|
||
|
|
Code can include C and C++ style comments:
|
||
|
|
// using the doubleslash comments until the end of the line
|
||
|
|
/* using the classic C comments
|
||
|
|
comment a block of text */
|
||
|
|
|
||
|
|
You can combine operators and functions into expressions, such
|
||
|
|
as:
|
||
|
|
x = 5 * cos(y) / 32.0; // this does some leetness right here
|
||
|
|
|
||
|
|
You can use multiple expressions by seperating them with one or
|
||
|
|
more semicolons, for example:
|
||
|
|
x = x * 17.0; x = x / 5; y = pow(x,3.0);
|
||
|
|
|
||
|
|
It is worth noting that extra whitespace (spaces, newlines) is
|
||
|
|
ignored, so if you need to space things out for clarity, you can.
