[Trigger] BlzGetMouseFocusUnit desync

I'm trying to use BlzGetMouseFocusUnit() for proper Unit Detection for Mouse Hover, it has to be Multiplayer compatible, I read that it causes desyncs because it stores the value locally and doesn't sync to others. Anyways is there a simple way to sync the udg_Temp_Unit or whatever must be synced?
I never used SyncMethods and need a explaination for these, they seem a bit complicated.

I don't know of a simpel way.
If you are willing to use jass (or lua, whatever you chooser) there is a way.

I would use a unit index system. Use a trigger with the sync event BlzTriggerRegisterPlayerSyncEvent to receive the index. Send it in a local Player block using BlzSendSyncData.

Made an example, in the SyncTrigger you would use the number to get back to the unit. (Didn't test it in multiplayer)

In theory you could use the unit handle, but sadly the handles are not synced between player which can lead to desyncs.
