Animation: comparison of three levels of destructibility

wkIndiMask is a module for WormKit that allows maps to be set up that have both destructible and indestructible parts to them.

There are 3 'types' of terrain, Destructible, Indestructible and Tough (only removed when an explosion occurs that will remove the background soil texture. E.g The center part of Dynamite or Holy Hand Grenade)

IndiMask settings for a map can be edited using MapGEN version 0.4.0 or later, or if you need more control, any paint package using the info below:

All info is stored in the PNG palette for the map. In order to set up a map for wkIndiMask, you must first ensure the palette has a particular entry. The module will search for this entry when a game starts and activate or deactivate based on its presence. Because WA throws away unused map palette entries, it will have to exist somewhere on the map. 1 pixel under the water is fine.

This colour is R:240, G:024, B:204. (  #F018CC)

After that, you can pick which colours are destructible or not using the least significant bit in the Red component of the colour. So essentially:

If the Red component is even, you can destroy it; if it is odd, you can't.

Further to that, the Green component is similarly used to decide if the colour is Tough.

A colour that has odd for both Red and Green will be set as Tough.

Quick reference table:

Effect	When red is:	and green is:
Terrain will be Tough	Odd	Odd
Terrain will be Indestructible	Odd	Even
No Effect / Normal Terrain	Even	Odd
No Effect / Normal Terrain	Even	Even

Tough terrain is only destroyed by a weapon where it would usually destroy the background layer.
