Can bash ?
 

Hi , do you know if function exist for know if you can bash if you have the distance for bash and if you have the resource for bash ?

No, no, yes :D

Only the ressources can be tracked via event
Add a filter to the event so it only applies to yourself (unittag: player), described here:

And maybe only track the stamina CombatMechanicType (powertype).
But how much stamina the bash costs is maybe not a fixed value! Not sure if one can determine this at all, I doubt it.
Depending on your race, class, passive skills, equipped skills it may cost more or less stamina to bash.

Hum ok , thx for this fast reply
