Need help creating projectiles for a platformer

[graycontrast]

I am trying to create a platformer game where you can run, jump and shoot projectiles (lemons like in megaman).

I am using 3-D models restricted to a 2-D plane. I already have my character running and jumping, however I am having a very difficult time trying to get shooting. I am not sure how to start. Should I have the chatterer controller script generate the projectiles? Can I make a global trigger that follows the character and emit the bullets? I am not sure where/how to generate the projectiles and where/how to do collision detection. can I have it shot a .pfb that I have made, or will it have to be a basic shape, or sprite? Thanks!

Prefab:Load and Script:Collision - this is all what you need.

See the bullet script, it will work with any entity.

I was able to create a prefab when pressing the fire button using the "Prefab:Load" however my problem now is that it spawns at the prefab's default position and direction. How can I get the player's position and direction so I can add a self.entity:SetPosition(x,y,z) and self.entity:SetRotation(x,y,z) to the projectile script? Is there a way to pass that to the prefab as I load it? Or will I have to search the world entries?

You can get the position of the player with

 

local pos = self.entity:GetPosition(true)

 

and the rotation with

 

local rot = self.entity:GetRotation()

[Genebris]

Prefab:Load returns created entity.

here is my function.

function Script:Fire()
local bullet = Prefab:Load("Prefabs/Projectiles/testBullet.pfb")
local pos = self.entity:GetPosition()
local rot = self.entity:GetRotation()
bullet:SetPosition(pos)
bullet:SetRotation(rot)
end

 

and I am getting an error that says " attempt to index local 'self' (a nil value)" when trying to use self.entity:GetPosition() or self.entity:GetRotation() I am not sure why self is nil in this function. those commands work in the other functions

[graycontrast]

I was able to get it to work. my call for the Fire function was wrong. it was self.Fire() not self:Fire()

[Genebris]

self.Fire() is also correct, but it doesn't send "self" to a function which resulted in your errors. When you use "self:Fire" you make "self" accessible inside this function.
