Functions

func EvaluateCombat

func EvaluateCombat(formulaJSON string, attacker *Resolver, attackerCtx *Context, defender *Resolver, defenderCtx *Context, rng func() float64) (float64, error)

func EvaluateCombatEx

func EvaluateCombatEx(formulaJSON string, attacker *Resolver, attackerCtx *Context, defender *Resolver, defenderCtx *Context, rng func() float64) (value float64, isHit bool, isCrit bool, err error)

EvaluateCombatEx evaluates a combat formula and also returns the "hit" and "crit" flags set by Flag nodes in the formula. rng supplies the random draws (0..1) the formula consumes, in evaluation order.

func LoadLibrary

func LoadLibrary(libPath string) error

LoadLibrary allows manually specifying the library path.
