Good day, reader. This mission is about dynamic indexing.
As we all know, dynamic indexing is one method used to achieve MUI. This snippet will help you understand how it works.
As our demonstration, we will have an active ability that damages a targeted enemy unit.
Per demonstration, the rawcode of the passive ability is
- v.1.0 - Creation of thread.
- v.1.1 - Changed the example from an AoE damage aura to a concentrated blast of damage dealt to a specific unit over 2.00 seconds.
- v.1.2 - Changed the example from damage to heal. Also removed the caster variable.
- v.1.2.1 - Added the Submission tag as it did not have one before...
