Combat

[Mario]

• Add a game log
• Add an attack action
• Implement basic combat mechanics

func attack(source, target) -> void:
    if attackHits(source, target):
        applyHits(source, target)

func attackHits(source, target) -> bool:
    var result = roll(source.dex)
    if result < 0.25:
        return false
    return (source.dex - (target.dex * 0.5) + result) > 4

func roll(sides: int) -> float:
    var result = (rand() * rand()) * sides * 0.5
    if result > (sides - 0.5):
        result += roll(sides)
    return result
