Approach conspecifics is directed movement towards a conspecific. More...
Public Member Functions | |
| procedure, public | init => approach_conspecifics_init_zero |
Initialise the approach conspecific behaviour to a zero state. Approach conspecific is a special extension of the generic the_behaviour::approach behaviour. See the_behaviour::approach_conspecifics_init_zero(). More... | |
| procedure, public | do_this => approach_conspecifics_do_this |
The "do" procedure component of the behaviour element performs the behaviour without affecting the actor agent (the_agent) and the world which have intent(in), so it only can change the internal representation of the behaviour (the type to which this procedure is bound to, here APPROACH_CONSPES). See the_behaviour::approach_conspecifics_do_this(). More... | |
| procedure, public | expectancies_calculate => approach_conspecifics_motivations_expect |
the_behaviour::approach_conspec::expectancies_calculate() (re)calculates motivations from fake expected perceptions following from the procedure approach_conspec::do_this(). See the_behaviour::approach_conspecifics_motivations_expect(). More... | |
 Public Member Functions inherited from the_behaviour::approach | |
| procedure, public | init => approach_spatial_object_init_zero |
Initialise the approach behaviour component to a zero state. Approach is a generic type but not abstract. See the_behaviour::approach_spatial_object_init_zero(). More... | |
| procedure, public | do_this => approach_do_this |
The "do" procedure component of the behaviour element performs the behaviour without affecting the actor agent (the_agent) and the world which have intent(in), so it only can change the internal representation of the behaviour (the type to which this procedure is bound to, here the_environment::approach). See the_behaviour::approach_do_this(). More... | |
| procedure, public | expectancies_calculate => approach_motivations_expect |
the_behaviour::approach::expectancies_calculate() (re)calculates motivations from fake expected perceptions following from the procedure approach::do_this() => the_behaviour::approach_do_this(). See the_behaviour::approach_motivations_expect(). More... | |
| procedure, public | execute => approach_do_execute |
Execute this behaviour component "approach" by this_agent agent. See the_behaviour::approach_do_execute(). More... | |
| Public Member Functions inherited from the_behaviour::move | |
| procedure(move_init_root), deferred, public | init |
The the_behaviour::move::init() is a deferred function that is overriden by each extension object init method. More... | |
| Public Member Functions inherited from the_behaviour::behaviour_base | |
| procedure(behaviour_init_root), deferred, public | init |
| Abstract init function that has to be overriden by each object that extends the root behaviour component class. More... | |
| procedure, public | is_executed => behaviour_root_get_is_executed |
Get the execution status of the behaviour unit. See the_behaviour::behaviour_root_get_is_executed(). More... | |
| procedure, public | gos_expected => behaviour_root_gos_expectation |
gos_expected is an accessor get-function that returns the final GOS expectation from expectancies_calculate. Once we get this value for all the possible behaviours, we choose what behaviour to execute by minimising gos_expected. See the_behaviour::behaviour_root_gos_expectation(). More... | |
| procedure, public | attention_transfer => behaviour_root_attention_weights_transfer |
attention_transfer transfers attention weights from the actor agent to this behaviour expectancy objects. See the_behaviour::behaviour_root_attention_weights_transfer(). More... | |
Public Attributes | |
| real(srp) | expected_food_gain |
| The expected food gain (body mass increment) is always null for active escape. More... | |
| real(srp) | expected_pred_dir_risk |
| The expected direct predation risk, from the nearest predator. More... | |
| real(srp) | expected_predation_risk |
| The expected general predation risk, i.e. the risk depending on the current number of predators in both the perception and memory stack. More... | |
| Public Attributes inherited from the_behaviour::approach | |
| real(srp) | expected_cost_moving |
| The body mass cost of movement; depends on the distance. More... | |
| Public Attributes inherited from the_behaviour::move | |
| real(srp) | distance |
| Movement is described by its absolute distance. More... | |
| Public Attributes inherited from the_behaviour::behaviour_base | |
| logical | is_active |
| Logical flag indicating that this behaviour is activated (executed). More... | |
| type(motivation) | expectancy |
| Each behavioural type within the whole repertoire has expectancies that set how each of the GOS motivational components is affected by its execution. More... | |
| real(srp) | arousal_expected |
An expectation of the arousal level. It is the maximum weighted value among all motivation components. This value is actually minimised – those behaviour which would result in the lowest arousal_expected is finally executed. More... | |
