Everything Burns

What will you mine when stone turns to fire?

What will you craft when diamonds crumble to ash?

What will you build... when Everything Burns?

This mod makes all blocks, except for fluids and waterlogged blocks, flammable. 

It's as simple as that. 

  

This is, essentially, the entire code of the mod:

@Mixin(FireBlock.class)
public class FireBlockMixin {
    public static final TagKey<Block> BURNING_NOT_MODIFIED = TagKey.create(Registries.BLOCK, ResourceLocation.fromNamespaceAndPath(MOD_ID, "burning_not_modified"));

    @ModifyReturnValue(at = @At("RETURN"), method = "getBurnOdds(Lnet/minecraft/world/level/block/state/BlockState;)I")
    private int modifyBurnOdds(int original, @Local(argsOnly = true) BlockState state) {
        return original <= 0 && !state.is(BURNING_NOT_MODIFIED) && state.getFluidState().isEmpty() && !state.isAir()  ? 30 : original;
    }

    @ModifyReturnValue(at = @At("RETURN"), method = "getIgniteOdds(Lnet/minecraft/world/level/block/state/BlockState;)I")
    private int modifyIgniteOdds(int original, @Local(args BlockState state) {
        return original <= 0 && !state.is(BURNING_NOT_MODIFIED) && state.getFluidState().isEmpty() && !state.isAir()  ? 60 : original;
    }
}
