Fair point, but I think it's trivial - something like "if hit, display animation 1/if miss, display animation 2". Idk, I could be wrong, I'm not a coder. Seems rather simple though, unless you want something more sophisticated, like when to dodge and when to block.
To take it one step further, I'd like characters to engage in combat animation whenever they "threaten" another combatant in melee range. Basically the two (or three or whatever) combatants would look like they are in battle.
So even if it's the fighter's turn, the wizard and the goblin standing next to each other would be "fighting" because they are in each other's threatened space. It could be as simple as a combat stance, but even better would be feints, swings, blocks, etc... make it look like they are fighting (or at least aware of each other's presence).
