Shovel Knight scripts

[SenL]

Hi,

I'm learning to mod this game.

I'm currently looking at/learning from "Shovel Knight" by BLsquared

(http://steamcommunity.com/sharedfiles/filedetails/?id=369544255&searchtext= ) 

 

Questions:

1)

In the shovelblade.lua, there is "MakeHauntableLaunch(inst)" inside local function fn(Sim).

What is this/what does this do?

 

2)

In the same file, there is "owner.AnimState:OverrideSymbol("swap_object", "swap_shovelblade", "swap_shovel")"

What are these 3 parameters?

 

3)

In the same file, there is "inst.components.tool:SetAction(ACTIONS.DIG)" and then later "inst:AddInherentAction(ACTIONS.DIG)" -- why these two?

 

There is "inst.components.tool:SetAction(ACTIONS.MINE, 2)" but nothing below regarding AddInherentAction to mine. Why?

 

Thanks!

Im no skilled programmer, but let me take a few wild guesses.

1. Im assuming this makes it where, of the available actions, whenever the Shovelblade is haunted, it will be launched across the screen similar to how a MooseGoose would knock items out of your inventory

2. If I recall correctly, these let the game know what images to use when displaying the shovelblade

3. This probably gives the Shovel the ability to dig similar to a normal shovel.
