Problem Description

Some servers have multiple version support , if OldCombatMechanics can Hook into ProtocolSupport/Viaversion to check players's clients version , and disable OldCombatMechanics for 1.9 and newer clients , just enable OldCombatMechanics for 1.8.9 and Legacy clients .
If this can be achieved , the plugin will more perfect !

So it would mean that some 1.8-combat players could fight with some 1.9-combat players. Same problem as here.

This sounds like you're asking for OldCombatMechanics to make 1.8.9 clients use 1.9+ mechanics, which is the opposite of what the plugin does. The plugin changes the server side mechanics for 1.9+ to make it like 1.8.

OldCombatMechanics only functions for 1.9 and newer clients because older versions already have the old mechanics. As @elstur said, are you trying to get 1.9+ combat for 1.8 and older clients?

I didn't mean that.
I mean , 1.9-latest clients use 1.9+ combat (disabled plugin function for these players), 1.8.9-legacy clients use old combat .
