-- Plantlife library mod by Vanessa Ezekowitz
Changed plants_lib API to require a table argument when not using legacy calling options. This opens the door for even more features in the future. Changed flowers, junglegrass, poisonivy to match. Made plants lib faster in some places, especially the surface-hunting algorithm, and especially over water. Fixed a few other misc. bugs. Made growth code properly execute all biome-control code before executing any string-named function or spawn_tree(). Tuned flowers settings. Made flowers require at least some light to spawn, made waterlilies require shallower water. Fixed a bug in water depth detection and made water depth depend on whether the bottom of the water area is dirt, dirt with grass, or sand, rather than just anything. Made waterlilies randomly rotate on spawning to break up the patterns (now has 16 orientations with the help of nodeboxes and facedir, requires only 3 new nodes). Smoothed edges of the regular waterlily texture. Made all flowers and water- lilies spawn using only 3 ABM calls instead of 8. Got rid of colon prefix node def overrides on all plants, since this is a modpack now instead of an integrated mod. Fixed a misspelled folder name for poisonivy. Fixed a bug in the wall detection routine - it returned the last wall found, not the first. Made the top-side-check for air only apply when spawning on top of the target rather than its sides/bottom. Many other features and enhancements have been made. Too many to list here. Please see API.txt for details.

Renamed the "plants" module to "plants_lib". Any modder that directly depends on that library need only adjust their mods' depends.txt files. I've already done this for flowers, junglegrass and poisonivy as included in this modpack, so any mod that depends on one of *those* needs no changes at all. No changes to the API or any functionality.

Extended the API yet again, this time adding a Perlin-based temperature map (two new variables defining min and max temperature, normalized to 0.53 = 0 degrees centigrade). The values used for this new Perlin layer come from Splizard's Snow Biomes mod, so other mods that use plantlife to create biomes should be able to blend nicely with that mod.

Added a function to let one spawn plants at mapgen time, but it's slow as molasses in January. Not recommended for general use yet.

Fixed a bug in water depth detection and made water depth depend on whether the bottom of the water area is dirt, dirt with grass, or sand, rather than just anything. Made waterlilies randomly rotate on spawning to break up the patterns (now has 16 orientations with the help of nodeboxes and facedir, requires only 3 new nodes). Smoothed edges of the regular waterlily texture. Made all flowers and water- lilies spawn using only 3 ABM calls instead of 8. Got rid of colon prefix node def overrides on all plants, since this is a modpack now instead of an integrated mod. Fixed a misspelled folder name for poisonivy. Fixed a bug in the wall detection routine - it returned the last wall found, not the first. Made the top-side-check for air only apply when spawning on top of the target rather than its sides/bottom. Many other features and enhancements have been made. Too many to list here. Please see API.txt for details.

Changed plants_lib API to require a table argument when not using legacy calling options. This opens the door for even more features in the future. Changed flowers, junglegrass, poisonivy to match. Made plants lib faster in some places, especially the surface-hunting algorithm, and especially over water. Fixed a few other misc. bugs. Made growth code properly execute all biome-control code before executing any string-named function or spawn_tree(). Tuned flowers settings. Made flowers require at least some light to spawn, made waterlilies require shallower water. Fixed a bug in water depth detection and made water depth depend on whether the bottom of the water area is dirt, dirt with grass, or sand, rather than just anything. Made waterlilies randomly rotate on spawning to break up the patterns (now has 16 orientations with the help of nodeboxes and facedir, requires only 3 new nodes). Smoothed edges of the regular waterlily texture. Made all flowers and water- lilies spawn using only 3 ABM calls instead of 8. Got rid of colon prefix node def overrides on all plants, since this is a modpack now instead of an integrated mod. Fixed a misspelled folder name for poisonivy. Fixed a bug in the wall detection routine - it returned the last wall found, not the first. Made the top-side-check for air only apply when spawning on top of the target rather than its sides/bottom.

plantslib:grow_tree(pos, grow_function)
Changed plants_lib API to require a table argument when not using legacy calling options. This opens the door for even more features in the future. Changed flowers, junglegrass, poisonivy to match. Made plants lib faster in some places, especially the surface-hunting algorithm, and especially over water. Fixed a few other misc. bugs. Made growth code properly execute all biome-control code before executing any string-named function or spawn_tree(). Tuned flowers settings. Made flowers require at least some light to spawn, made waterlilies require shallower water. Fixed a bug in water depth detection and made water depth depend on whether the bottom of the water area is dirt, dirt with grass, or sand, rather than just anything. Made waterlilies randomly rotate on spawning to break up the patterns (now has 16 orientations with the help of nodeboxes and facedir, requires only 3 new nodes). Smoothed edges of the regular waterlily texture. Made all flowers and water- lilies spawn using only 3 ABM calls instead of 8. Got rid of colon prefix node def overrides on all plants, since this is a modpack now instead of an integrated mod. Fixed a misspelled folder name for poisonivy. Fixed a bug in the wall detection routine - it returned the last wall found, not the first. Made the top-side-check for air only apply when spawning on top of the target rather than its sides/bottom. Many other features and enhancements have been made. Too many to list here. Please see API.txt for details.

Renamed the "plants" module to "plants_lib". Any modder that directly depends on that library need only adjust their mods' depends.txt files. I've already done this for flowers, junglegrass and poisonivy as included in this modpack, so any mod that depends on one of *those* needs no changes at all. No changes to the API or any functionality.

finished splitting up the three components into separate folders, by moving texture files to their respective components' folders (<f>/textures). Also, began working on extending the API for the growing code to allow for checking for the height of a node. Poisonivy is the only component that uses it for now; this is more intended to be used with nature pack eventually.
