The object was to make it easier to follow, and to also remove fruit spamming. The attribute "fruitsMax" now denotes the maximum number of fruits in the plant at any given time. "fruitsChance" now denotes a percentage, i.e. [0, 100]. The closer to 100 the greater the chance of a fruit being created or dropped each tick. The existing fruiting entities were also altered to make them produce less fruits, to prevent spamming.

/// Most of the functionality will be common to all plants, and most

/// derived classes will probably be in python. Provides functionality
|
|
/// for producing and dropping fruit very simply.
|
|

|
|
/// The basic functionality of Plant is as follows:
|
|
/// 1) The plant receives a tick operation. It checks it's m_nourishment value to see
|
|
/// whether it should grow or wither.
|
|
/// If the plant has fruitName set, it will also do a check whether it should drop a fruit or not.
|
|
/// It also sends an Eat operation to it's parent.
|
|
/// 2) If the parent is the world, the world will respond to the Eat operation by checking
|
|
/// if the plant is in a favourable spot (i.e. a place where it can grow, like in the bare ground).
|
|
/// If so, the World will send a Nourishment op to the plant.
|
|
/// 3) The plant receives the Nourishment op and adds its value to m_nourishment.
