Modifying initial energy of a creature as a result of its genes (Ee) is in general not a good idea. Weight (Ww) works only in water, and in water sinking/going up should usually be caused by real "intentional" activity of a creature, not by its inherited weight. For assimilation (Aa), there is a dedicated parameter in CreaturesGroup. Stamina (Ss) is no longer needed as destructive collisions are not supported, and even if they were, some expdef would need to impose reasonable restrictions on the value of this parameter (e.g. similar to normalizeBiol4()) so there is some cost associated with it, and the specific consequences of destructions should be defined as needed.
24 * Contains physical, biological and other properties of
25 * stick, except for rotation. The constructor initializes properties of sticks with
26 * default values. In order to change a property of a stick, the executeModifier() method
27 * should be called. Modification of length, curvedness and twist properties
28 * usually affects further sticks, so new sticks should have properties of
29 * parents (prop) modified with the prop.propagateAlong() method.
30 * "Biological" properties (assimilation, stamina, muscle strength and
31 * ingestion) should be normalized after modification with normalizeBiol4().
