createAsteroid

SpaceObject createAsteroid(CoordI2 dimension,
                           WorldManager worldManager)

Create an asteroid composite entity

createAsteroid

<T extends AbstractCompositeEntity> T createAsteroid(Class<T> clazz,
                                                     String defNamePrefix,

                                                     WorldManager worldManager)

Create an asteroid composite entity

Parameters:

clazz - Composite entity class type to return. Use SpaceObject if in doubt

defNamePrefix - Prefix to choose from entity definitions. Use ASTEROID_STANDARD_PREFIX if in doubt

defNameSuffixes - Suffixes to choose from different asteroid types (suffix must be part of the entity def name). Use ASTEROID_STANDARD_SUFFIXES if in doubt

dimension - Size of the asteroid

place

boolean place(AbstractCompositeEntity compositeEntity,
              CoordI2 position,
              WorldManager worldManager)

Places an asteroid at a certain position. Checks e.g. if space is free

place

boolean place(AbstractCompositeEntity compositeEntity,
              Area2 area,
              WorldManager worldManager)

Places an asteroid in a certain area. Checks e.g. if space is free

placeAsteroidBelt

List<SpaceObject> placeAsteroidBelt(int sizeMin,
                                    int sizeMax,
                                    double density,
                                    double velocityMin,

                                    WorldManager worldManager,
                                    BiPredicate<MutableCoordI2,CoordI2> randomPositionPredicate)

Generates and places a whole belt of asteroids

Parameters:

sizeMin - Min size of asteroids

sizeMax - Max size of asteroids

density - Density of asteroid belt, values between 0.0 and 1.0

velocityMin - Min velocity, can be 0.0

velocityMax - Max velocity, can be 0.0

vDirectionNorm - If asteroids should have a velocity, set a normal vector (length 1) here to indicate the direction

area - Area to place the asteroid belt in

randomPositionPredicate - Generates the position of the next asteroid to be spawned (set coordinates in first argument MutableCoordI2 "by ref", this is a mutable variable). Return false to abort.

calcVDirectionNormByGameSessionId

CoordD2 calcVDirectionNormByGameSessionId()

Returns a normal direction vector. It stays the same for the game session. Can be used for example as direction vector in placeAsteroidBelt()
