(b1.2 - 13w01b) Fire 1

[muzikbike]

There is evidence pointing to there being two coexisting fire textures at least as early as Beta 1.2:

• Beta 1.2 introduces a second fire placeholder texture to terrain.png
• In modern versions (13w02a and up) there are two fire textures: fire_0.png and fire_1.png.

I'm not sure how differently they're generated, though - possibly a different initial seed? It seems likely that they use the same algorithm, but again I could be wrong.

As the fire texture very likely used RNG for generation, it may vary between sessions and getting a loopable animation may not be possible.

Completely random thoughts: I wonder if it'd be possible to generate a pre-1.5 analogue of soul fire by tweaking some values.

Also, I do not think this program should cover mods (perhaps a sister project could), but blue fire from the beta Ice Mod was also generated by the game procedurally.

Also, should I report MT19937 versions of textures (aka the Pocket Edition versions of water, lava, ...) separately?

Some investigations in Beta 1.7.3 with the following terrain.png to try and determine what each texture is used for. What I believe corresponds to fire_2 is recolored to blue.

Northwest and southeast facing directions appear to yield identical results:

Straight north:

The fire overlay:

May test in 1.5-1.7 to see if the results match.

This is in the process of being done.

The Pocket Edition case has been split into #28.
