Math operations

Hi,

Is there an easiest way to do mathematical operations than using functions add, sub, mul and div ?

A simple exemple of what I want to do :

add(st_opt.first_x,st_opt.x,st_opt.half_width);
mul(st_opt.first_x,st_opt.first_x,2);
sub(st_opt.first_x,st_opt.first_x,st_opt.control_width);
sub(st_opt.first_x,st_opt.first_x,tmp_half_thumb_width);

Is there a way to do something like :
set(st_opt.first_x, eval(2 * (st_opt.x + st_opt.half_width) - st_opt.control_width - tmp_half_thumb_width));

Another thing I was asking me is : is there a way to specify my own basedir (not like %CURRENTXML% but a real path) ?

Thank

A.L.

Hi,

no, but with the latest version, the math actions can also be used just with two parameters,
(see the releasenotes.txt)

e.g. this would reduce the code to this:

Source code

 
1
2
3
4

add(st_opt.first_x, st_opt.x, st_opt.half_width);
mul(st_opt.first_x, 2);
sub(st_opt.first_x, st_opt.control_width);
sub(st_opt.first_x, tmp_half_thumb_width);


best regards,
Klaus

Math Operations

Maybe a stupid question ( Isn't that always how they start) but when would you use these functions?

@Klaus : thanks for your response

@adamsheha2 : I was generating dynamic XML configuration and I have created a thumbnail script (only with actions, no swf plugin). There is a lot of math operations for placing thumbnails correctly.
