Add a single tick to the current incubation period. Called by the game engine each tick after the creature starts reproducing. Once the amount of ticks hits the limit for the amount of time required to incubate a child, the creature is born, and incubation is no longer required.

Adds a single tick to the creature's current age. This is also responsible for ticking down other counters like growth and reproduction. When ticks hits the LifeSpan the creature dies, but when the other counters reach 0 the action becomes available.

Used by the game engine to burn a creature's energy depending on the various actions they perform including movement, reproduction, and growth.

Clones the current plant state while resetting the immutability attribute so that the new state can be updated with new information.

Compares two organism state objects together. This method takes into account the Y position for graphical Z-Ordering purposes and can be used to sort creatures for back to front rendering.

Determines whether the specified Object is equal to the current Object.

Serves as a hash function for a particular type.

Gets the Type of the current instance.

The amount of energy a plant gets decreases linearly as you get away from the optimal

Used by the game engine in order to grow a creature. This attempts to grow the creature's radius by one unit. It makes a copy of the organism state rather than modifying it directly since the size and location properties might be immutable.

Plants heal just by getting their foodchunks back up to the maximum level -- kind of like growing their old leaves back. This should only be called by the game engine and so the method is protected by the immutable property.

Increases the radius of the creature to a new radius. The game engine calls this whenever a plant grows. Since plants have other attributes that change the base implementation of this method must be overriden to also update the foodChunks property.

Used to compute whether or not a given state object is in an adjacent or overlapping grid cell. The extra radius can be used to extend the area used for the function to find a match and so can be used for functions like visibiliy.

Called by the game engine in order to kill the current creature. Since this method can only be called when the state is mutable player's can't use the method to arbitrarily kill competing organisms.

Performs a special type of immutability lock for the size and position related properties only. This is to ensure that the area of a creature isn't changed after the creature's index array position has been found in the game world.

Makes all properties immutable. Ensures that the organism state cannot be changed at all by creatures with access to the state.

Used by the game engine to reset the amount of time the creature must wait before growing. The wait time is based on the creature's species class which uses the creature's lifepsan as a base for the growth period. This should be called after a creature has been given the chance to grow, and must wait before growing again.

Sets the current reproduction wait of the creature to the wait time specified by the creature's species. This value will be set based on the creature's lifespan and creature type (whether carnivore or herbivore). This is called by the engine after reproduction has completed.

Returns a string that represents the current object.
