about command's poblen

#1

hi, I saw a command script in Spinder_Setup.fxs like this:

[SP01_Base:xwpos@NOW+0.1]-[SP01_Base:xwpos]

do you know what’s meaning about it? and what is [b][i]xwpos@NOW[/i][/b] ?

thanks

It’s not just the ‘NOW’ but ‘NOW+0.1’.

The command NOW reads the value at the current frame, NOW+0.1 reads the value 0.1 frames ahead.

So in this case, the part of the expression [SP01_Base:xwpos@NOW+0.1] is reading the world (global) x position of the item ‘SP01_Base’ 0.1 frames ahead of the current frame.
