###Usage Examples

<expr>{global = if(global==0, 45, global)}</expr>

Allows to execute expressions. Since it is also possible to assign variables inside expressions, more complex algorithmic constructions are possible.

<anim name="anim1" duration="10s" fadeout="2s">
    <track name="t1" fadeto="{log(global)}">0. {global}</track>

<track> in combination with <anim> creates two variables that changes its value over time, from the first set value (0) to the last set value ({global}) in 10 seconds.

the name of the first variable is t1 and can only be used inside the <anim> command. the name of the second variable is anim1.t1 and can be used inside the <que> command (as soon as the <anim> node was executed)

    <send>/sendadress command {t1} {anim1.t1}</send>

this <send> command references the created values and creates a send message.

</anim>

<wait until="{anim1.t1 > (var_1 / 2)}"/>

the <wait> command waits until the value of the variable anim1.t1 is greater than half of val_1. If this <wait> command was right after the <anim> command, it would wait for 5s before the script carries on, because it takes the <anim> command 10 seconds to reach var_1 for the variable anim1.t1.
