Modding Help How to make projectile fire based on way you're looking?

As the title says.
I've tried "flippable" : true, but that doesn't seem to have done it.
Maybe missed it somewhere though, dunno.

I'll look into it, but I usually find it once I make a post like this... hah.

 

I've never seen this not be the case. Share the file you are working on?

 

Sure, I'll link it right as soon as I get to my computer again.

 

Here y'are, maybe you can figure it out.
I'm sorta stuck.

 

Oh yeah, should have mentioned, this problem is with the human tier 1-2 staff, apex tier 1-2 staff and the glitch tier 2 staff, that probably would've been useful to know.

 

you just want it to fire straight? not follow the cursor like the other staves?

 

Yep, pretty much.

 

havent figured it out yet, am still tinkering

 

Aight, that's fine. Thank you for the help so far.

 

Call this a decent guess. I haven't tested it. Things could be backwards(270 instead of 90) etc.

Lets look at weapon.lua
line 124

Code:

local aimAngle, aimDirection = activeItem.aimAngleAndDirection(self.aimOffset, activeItem.ownerAimPosition())

That isn't apparently what you want.

So suppose I gave you this function

Code:

facing_aimAngleAndDirection = function(t1, t2)
  if ((t1[1] - t2[1]) < 0) then
    return 90, -1
  else
    return 90, 1
  end
end

You might call it like this

Code:

local aimAngle, aimDirection = facing_aimAngleAndDirection(mcontroller.position(), activeItem.ownerAimPosition())

Perhaps that will get you somewhere. I replacing that bit of code would have a weapon that fires straight ahead. It is possible that I misunderstand your intent though.
edit: easier way. I forgot about mcontroller.facingDirection()

 

Thanks for the info! Unfortunately I'm not all that experience paced with Lua, so I wouldn't know what to do with that code...
How would I go about using mcontroller.facingDirection though?
Thanks again!

 

mcontroller.facingDirection(), you only have to put that in, facingDirection() takes no arguments, it however outputs a 1 if facing the right and a -1 if looking left. This is usually used to tell the game which direction some projectile should go. If you need anything else I can check it, plus I've been reading all these over for awhile.

 

Thanks for that info! However, I still don't know what to do with that code...
Does it go in the .activeitem file or the lua? And if in the lua... where / how?
Thanks in advance!

 

In the lua, usually used as a multiplier (against projectile velocity) to tell which direction to go. Like "projectileVelocity * mcontroller.facingDirection" as a terrible example.

 

Okay, but, where about sin the lua? At the bottom? Or a certain place?
And, weapon.lua? Or some other?

Thanks again.

 

I'm gonna need a reference, I'm on my phone so I can't really say, I understand what your sayin now, I'll be back tomorrow with a proper answer unless someone else does first, then in that case... Rood.

 

Aight, well, thanks again.
Heh.

 

So in staffs (function ControlProjectile:createProjectiles())

Code:

local fireDirection = world.distance(aimPosition, self:focusPosition())[1] > 0 and 1 or -1

But you're looking for a straight firing staff? Then in gunfire.lua you'll see

Code:

function GunFire:aimVector(inaccuracy)
  local aimVector = vec2.rotate({1, 0}, self.weapon.aimAngle + sb.nrand(inaccuracy, 0))
  aimVector[1] = aimVector[1] * mcontroller.facingDirection()
  return aimVector
end

This is the part that tells the bullet to move in the direction that you're aiming, if that's not enough then you can read into the whole gunfire.lua file

 

So, if I am not mistaken, in the staff lua, I'd see that code, and I'd replace it with the code you gave from the gunfire lua?
Or...?
Thanks again!

 

If you are looking to make the staff fire in a straight line, then yeah, use the gunfire lua in the staff's lua code, you may need to do a lot of tweaking to get it to work right.
