I present to you my...
On Attack Template 1.30:
a simple system that allows you do to some great things
What does this do?
In the absence of a better method for damage detection using GUI;
This allows you leverage the event "a unit is attacked", and both efficiently and accurately, detect when the target takes damage, and deal effects to said unit.
Sounds like fun no..??
Ok then hurry up and try it out!!
Version History:
enjoy!

Version History:
- 1.30 - Updated for 1.24 compatibility, removed dated CSData and CSSafety requirements, re-arranged and shorten code a bit, optimized trigger execution function, added theoretical destroytrigger() bug aversion configurable
- 1.20b - Updated to CSData and CSSafety 15.0, added in a new demo ability to showcase usage of the On_Attack_Template_Function call, Demo 3 updated slightly, few minor readme/documentation errors updated
- 1.2 - Ported to vJASS, slightly updated readme, removed demo 4 ability from test map
- 1.1 - Added greater functionality
- 1.0 - Initial Release
