Ability with relative facing

[ZombieKnight]

Hi,
Woking on some custom abilities;
How to check if unit is attacked from the face/right-face/left-face side before combat in formula?
(I'd like to increase unit's resistance/damage if it's attacked from the front)

FACE HEXES: those pikemans are on
BACK HEXES: those Assassins are on

I'm sure there's a more elegant way to do this, but...

You dwarf is facing NE. Therefore, if (enemy.x>unit.x) or (enemy.x==unit.x and enemy.y>unit.y) then front=true.

I assume there will be special cases due to the hex coordinate system, but you can still brute force it easy enough if you think through them.

EDIT: Ignore this. You can do it with WFL. Looks like it would be pretty easy once you figure it out. See https://wiki.wesnoth.org/Wesnoth_Formul ... _Functions

Face hex means n,ne,se, so you could check if relative position between units is one of them.

Thanks I can use direction_from to get the faced hex and then tiles that are adjacent to both the unit and the faced hex are face-hexes and rest are back hexes.

But how to put it into weapon special/ability?
Since facing of the defender changes when the fight begins.

I was thinking about using direction_from to get the faced hex, then using direction_from with rotate_loc_around +1 and -1 on facing to get the others, but adjacent sounds like it would work too.

Here's an example of a weapon special that uses WFL and direction_from that might help...

Thats something else.
I t only checks if theres a unit on the other side of the target.
It doesn't work with the defenders unit facing.
And I don't know how to filter that...
Any ideas?

Yes, it's something else. It's just an example meant to show using facing and direction_from in a weapon special.

I assume to get defender's unit facing you'd move other.facing into [filter_self], or use self.facing in [filter_opponent].

But won't that relative facing set to face the attacker at the very start of the fight?
...
So you can't filter if he was attacked from his back side.
