This is what I have.



I would like it whenever my hero gains a level, he gains 3 Attribute Points to allocate to his attributes.

Is this possible through
a) Triggers.
b) Data Editor/Abilities?
c) or will I have to use stackable Buffs instead of Behaviours for my Attributes and then display their values in a Dialog box?

This may help.

Hey. I've managed to do it.

Not the way I would have wanted but I suppose it works.

• 3 Behaviour - Attributes
  
• Agility (move & attack speed)
  
• Strength (hitpoints & carrying capacity)
  
• Psionics (energy & energy regeneration)
  

• 3 Behaviour - Buffs
  
• Increased Agility (Modifier>Behaviour>Attribute>Agility>+1
  
• Increased Strength (Modifier>Behaviour>Attribute>Strength>+1
  
• Increased Psionics (Modifier>Behaviour>Attribute>Psionics>+1
  

And then a long discourse into Dialogue Menus, Items, Texts etc... for players to spend 'Attribute Points' on their Attributes.

The Buff is applied to the Hero unit when he chooses to spend a point on Agility for example. The Buff is Stackable up to 255 times. (Think of Stacking Poison in Warcraft 3 - except, these buffs only modify an Attribute, instead of dealing Damage over time)

I just can't seem to find a way to 'Hide the UI-Icon associated with a Buff'...

Its under the flags for the behaviour.
