Need help, script to run on monster's death.

[zadkielmodeler]

I am at the point where I want to run a script that activates when a person defeats a monster. Basically to congratulate that person on beating the game.

I know how to make the script play a sound, but not as triggered by the death of a monster. I am curious what the setup would be code-wise.

[crisman]

You should use a onDie hook in the monster definition asset.
Just clone a monster in monster.lua and add that function.

for example:

cloneObject{
name = "snail_boss",
baseObject = "snail",
onDie = function (self)
script_monster:script_death()
return true
end
}

in the editor you will place a script entity and call it script_monster, inside of it you will place the function script_death()
when the monster dies, the function wil be called.

I see so half the code goes into the monster itself and the other half is called by the monster onDeath. Thanks.

[zadkielmodeler]

Can I just call a lua function that is defined in the editor from monsters.lua or does the whole thing have to be done in monsters.lua?


Also, what is the purpose of return true in the code?

[zadkielmodeler]

yeah putting this

Code: Select all

	onDie:( function beatgame()


 playSound("discover_spell")
 showText("Congratulations. You have truly beaten this game. I hope you enjoyed it =) ")

end),

in the monster I have cloned does not work. =(

I see this asset Definition reference would have been so very useful, so much sooner. Thank you so much. =)

Okay the editor likes it all. but when it gets time to call the script, the game crashes. Here is the error log.

Code: Select all

#beatgame_script:5: attempt to call global 'showText' (a nil value)

This is the code I have in my monsters.lua for the monster.

Code: Select all

defineObject{
	name = "HighCouncelor",
	class = "Monster",
	model = "assets/models/monsters/goromorg.fbx",
	meshName = "goromorg_mesh",
	animations = {
		idle = "assets/animations/monsters/goromorg/goromorg_idle.fbx",
		moveForward = "assets/animations/monsters/goromorg/goromorg_walk.fbx",
		strafeLeft = "assets/animations/monsters/goromorg/goromorg_strafe_left.fbx",
		strafeRight = "assets/animations/monsters/goromorg/goromorg_strafe_right.fbx",
		turnLeft = "assets/animations/monsters/goromorg/goromorg_turn_left.fbx",
		turnRight = "assets/animations/monsters/goromorg/goromorg_turn_right.fbx",
		attack = "assets/animations/monsters/goromorg/goromorg_attack.fbx",
		getHitFrontLeft = "assets/animations/monsters/goromorg/goromorg_get_hit_front_left.fbx",
		getHitFrontRight = "assets/animations/monsters/goromorg/goromorg_get_hit_front_right.fbx",
		getHitBack = "assets/animations/monsters/goromorg/goromorg_get_hit_back.fbx",
		getHitLeft = "assets/animations/monsters/goromorg/goromorg_get_hit_left.fbx",
		getHitRight = "assets/animations/monsters/goromorg/goromorg_get_hit_right.fbx",
		fall = "assets/animations/monsters/goromorg/goromorg_get_hit.fbx",
	},
	--attackAnimSpeed = 1.7,
	moveAnimSpeed = .9,
	turnAnimSpeed = 2.5,
	movementCoolDown = .3,
	moveSound = "goromorg_walk",
	footstepSound = "goromorg_footstep",
	attackSound = "goromorg_attack",
	hitSound = "goromorg_hit",
	dieSound = "goromorg_die",
	hitEffect = "hit_dust",
	capsuleHeight = 0.8,
	capsuleRadius = 0.25,
	collisionRadius = 0.8,
	health = 2200,		-- goromorg shield is on top of this
	sight = 4,
	seeInvisible = true,
	allAroundSight = true,
	attackPower = 50,
	protection = 2,
	rangedAttack = { 45, "lightning_bolt_greater", 25, "ice_shards", 20, "fireball_greater", 10, "poison_bolt" },
	coolDown = { 3, 4 },
	movementCoolDown = .9,
	exp = 10000,
	onDie = function (self)
    beatgame_script:beatgame()
    return true
    end,
    

	
	particleSystem = "goromorg_lantern",
	particleSystemNode = "light1",
	lightName = "light1",
	lightColor = vec(7.5, 1.0, 2.5),
	lightBrightness = 4,
	lightRange = 4.5,
	healthIncrement = 90,
	brain = "Goromorg",
}

And this is the code I have in my lua script in the editor. It is in an entity called beatgame_script

Code: Select all

function beatgame()


 playSound("discover_spell")
 showText("Congratulations. You have truly beaten this game. I hope you enjoyed it =) ")

end

Please tell me what I messed up on.

[crisman]

it's not showText, but
hudPrint("Congratulations. You have truly beaten this game. I hope you enjoyed it =) ")

[zadkielmodeler]

Thank you so much Crisman. It works. Thank you so much. It works =)

[crisman]

No problem! Glad I could help
