The width in pixels of the main trunk

The total height of the combined trunk segments

The height in pixels of each vertical trunk segment (Does not affect overall height)

The random horizontal deviation in pixels, to shift each trunk segment as it 'grows' upwards

Trunk & Branch texture. The sprite id used for the mesh fill algorithm

• Sprite id's 0-15 (the top row of tiles) can be selected to change the tree's texture. These can be customized in the sprite editor to your liking

The average length in pixels of each branch

The width in pixels of each branch segment as the branch grows outwards

The height in pixels of each horizontal branch segment, as the segments 'grow' outwards

The height (in number of trunk segments), to snap branches to the nearest vertex of the main trunk

The random range in pixels that the branches are allowed to shift upwards at each growth step in the generation process, (lower values lead to straighter branches)

The total amount of branches to spawn (distributed evenly between the left and right of the trunk)

The relative offset between branches, scaled based on the number of branches and offset by the branch height parameter

The average chance that leaves will spawn. Leaves are spawned starting from the tip of each branch, snapped to branch vertices, going towards the trunk

The distance (in number of branch segments) from the tip of each branch toward the tree's trunk, to limit leaf drawing

The radius in pixels to randomly spread leaves (separate from leaf generation on branches). Always locked to the top of the tree trunk

The total amount of tries to randomly distribute leaves within the fill radius

The total amount of vines to spawn. Vines are spawned by picking vertices of two randomly selected branch segments and have a random 'sag' amount to vary the look

The sprite id to use for the layer of fruits/flowers. These are spawned using the same leaf-spawn method for the branches. In the sprite editor, sprite id's 32 - 47 are used for this layer - the third row.

Average chance to spawn fruits/flowers

In pixels, the rectangular area of SCREEN RAM to copy to SPRITE RAM using MEMCPY

The top-left corner of the rectangular area to copy & save.

Ranged 0 - 511 - The tile/sprite id to paste the copied rectangle. Keep in mind if the id is positioned near the border in the sprite editor, the copied tiles won't retain their original order

The current background color (for transparency reasons) - will be copied as the background when saving the tree
