Use setPosition() and/or setWorldPosition() on the object immediately after spawning it.

I can't figure how to do this correctly!
based on the ion spell, I have tried this:
but it works only when the party is facing 0, and the monster is in front of the party.
for the other directions, the spell is not on correct position. I 'm not sure on how the setWorldPosition works.
Code: Select all
class = "MonsterAttack",
name = "rangedAttack",
-- attackType = "projectile",
attackPower = 50,
minDistance = 2,
cooldown = 4,
animation = "rangedAttack",
sound = "lindworm_roar",
-- shootProjectile = "magma_meteor",
onAttack = function(self)
local dx,dy = getForward(self.go.facing)
local x = self.go.x + dx*2
local y = self.go.y + dy*2
local spell = spawn("magma_meteor", self.go.level, x, y, self.go.facing, self.go.elevation)
local wpos = spell:getWorldPosition()
local dx = nil
local dz = nil
if spell.facing == 0 then
dx = left and -0.1 or 0.1
dz = -1
elseif spell.facing == 1 then
dz = left and 0.1 or -0.1
dx = -1
elseif spell.facing == 2 then
dx = left and 0.1 or -0.1
dz = 1
else -- spell.facing == 3
dz = left and -0.1 or 0.1
dx = 1
end
spell:setWorldPosition(vec(wpos[1]-0.65,wpos[2]+0.25,wpos[3]+dz))
end,
can you help a bit please?

World position has global orientation, it is independent of facing. You have to adjust it depending on the facing of the caster. Your code is treating it as if the x position is local and the z position is global. All 3 positions are global. Also, you need to get rid of the lines with "left" because it will always be nil and only makes sense when it's a champion from the party casting the spell.
Also you need to check that your x and y positions are inside the map bounds, your current code will probably cause a crash if the lindworm breathes while on the edge of the map.

thanks,
so far I ve modified the above script into this: don't know if this is good, but it works on all direction.
Code: Select all
{
class = "MonsterAttack",
name = "rangedAttack",
attackPower = 400,
minDistance = 2,
cooldown = 3,
animation = "rangedAttack",
sound = "lindworm_roar",
onAttack = function(self)
local dx,dy = getForward(self.go.facing)
local x = self.go.x + dx*2
local y = self.go.y + dy*2
local spell = spawn("magma_meteor", self.go.level, x, y, self.go.facing, self.go.elevation)
local wpos = spell:getWorldPosition()
if spell.facing == 0 then
spell:setWorldPosition(vec(wpos[1]+0.65,wpos[2]+0.25,wpos[3]+0))
elseif spell.facing == 1 then
spell:setWorldPosition(vec(wpos[1]+0,wpos[2]+0,wpos[3]-0.65))
elseif spell.facing == 2 then
spell:setWorldPosition(vec(wpos[1]-0.65,wpos[2]+0.25,wpos[3]+0))
else -- spell.facing == 3
spell:setWorldPosition(vec(wpos[1]+0,wpos[2]+0,wpos[3]+0.65))
end
end,
},
I have no idea how to check positions. Can you help pls?

make sure your final x and y are not negative or above 31
also why do you have the Y position different for different directions?

lol I don't know
while trying how to represent that in a 3d space and use some values, I finally adjust it to that, and this works nice.
Code: Select all
spell:setWorldPosition(vec(wpos[1]-0.65,wpos[2]+0.25,wpos[3]+0))
did I understand this correctly?
here wpos[1] is the x , [2] the y , and [3] the z? or that does have nothing to do with that.
I'm kinda lost now!

In Grimrock, the X world axis is west to east, the Y world axis is down to up, and the Z world axis is south to north. So for adjusting the world position position of a fired projectile, you'll want to change the X and Z positions depending on the facing of the monster. But the monster's animation will always be making the attack at the same
height, regardless of which direction it's facing. So the Y world position, relative to the monster's Y position, should always be the same, and should not depend on facing.
It is a little strange since for
map coordinates (the ones used by teleporters, GameObject:setPosition(), and so on), X is west to east and Y is north to south. And in 3D modeling programs the Z axis is usually the down/up one. But this is just the way things are in Grimrock.

How do the comments this boss makes during the fight work ? Is it linked to its brain, or some script ? I would like him to comment on other spells casts in addition to the meteor storm...
