Suggest to add the placeholder support to the orbital mechanic

Summary

Suggest to add the placeholder support to the orbital mechanic.

Usage Using placeholder and variable in skill mechanics

• orbital{i=1;radius=3;point=264;onStart=FireStarter;onTick=FireStarterTick;onHit=FireStarterHit;onEnd=FireStarterEnd;duration=15;oy=1;rz=90;rx=<trigger.var.horizontal>} @origin

Value

<xxx.var.xxx> inside the skills

Priority

I think this can change the skills according to the player and the monster's orientation, giving a lot of room for customization.

Implementation

Just like other placeholders, the int or float value is calculated before the skill is released, and this value is substituted into the skill parameter, and then the cache is cleared after the release is over
