Public Member Functions

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...

type(motivationexpectancy
 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...

Member Function/Subroutine Documentation

◆ init()

procedure, public the_behaviour::approach::init

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().

Definition at line 302 of file m_behav.f90.

◆ do_this()

procedure, public the_behaviour::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().

Definition at line 309 of file m_behav.f90.

◆ expectancies_calculate()

procedure, public the_behaviour::approach::expectancies_calculate

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().

Definition at line 314 of file m_behav.f90.

◆ execute()

procedure, public the_behaviour::approach::execute

Execute this behaviour component "approach" by this_agent agent. See the_behaviour::approach_do_execute().

Definition at line 317 of file m_behav.f90.

Member Data Documentation

◆ expected_cost_moving

real(srp) the_behaviour::approach::expected_cost_moving

The body mass cost of movement; depends on the distance.

Note
Note that such class attributes as expected_food_gain, expected_food_gain expected_pred_dir_risk expected_predation_risk should be implemented in specific derived subclasses of the_behaviour::approach, e.g. the_behaviour::approach_conspec.
