nullifier.lua - Un-draw the environment

[Emral]

A script I once created for someone. The idea is to have a BGO which un-draws parts of the environment.

Example:
In this example, the nullifier BGO is on a moving layer. On the lefthandside you can see the editor setup, while on the right they have moved a bit. Here, anything above the background until blocks is hidden.

Spoiler: show

Docs (also in the file):

Code: Select all

-- set nullifier.id to the BGO ID you would like to use.
nullifier.id = 5
--call addRange to select what range of priorities you want to hide. In this example, the player is hidden
nullifier.addRange(-26, -24)

This seems interesting, i wonder what kind of stuff can you design around it.

We can do the SMW poison bubble shader now where it cuts through the scenery! good

Not with nullifier! Nullifier just does squares. Circles are a bit more tricky.

I'm a bit unsure by what this does. What do you mean exactly, by "un-draws the environment."?

It could easily be adapted to use a shader that cuts out a circle. Could also take a look at Sprite.circle, since that generates UVs for circle-shaped polygons.
