KX_GameObject(SCA_IObject)

base class — SCA_IObject

class bge.types.KX_GameObject

All game objects are derived from this class.

Properties assigned to game objects are accessible as attributes of this class.

Note

Calling ANY method or attribute on an object that has been removed from a scene will raise a SystemError, if an object may have been removed since last accessing it use the invalid attribute to check.

KX_GameObject can be subclassed to extend functionality. For example:

import bge

class CustomGameObject(bge.types.KX_GameObject):
    RATE = 0.05

    def __init__(self, old_owner):
        # "old_owner" can just be ignored. At this point, "self" is
        # already the object in the scene, and "old_owner" has been
        # destroyed.

        # New attributes can be defined - but we could also use a game
        # property, like "self['rate']".
        self.rate = CustomGameObject.RATE

    def update(self):
        self.worldPosition.z += self.rate

        # switch direction
        if self.worldPosition.z > 1.0:
            self.rate = -CustomGameObject.RATE
        elif self.worldPosition.z < 0.0:
            self.rate = CustomGameObject.RATE

# Called first
def mutate(cont):
    old_object = cont.owner
    mutated_object = CustomGameObject(cont.owner)

    # After calling the constructor above, references to the old object
    # should not be used.
    assert(old_object is not mutated_object)
    assert(old_object.invalid)
    assert(mutated_object is cont.owner)

# Called later - note we are now working with the mutated object.
def update(cont):
    cont.owner.update()

The ray is always casted from the center of the object, ignoring the object itself. The ray is casted towards the center of another object or an explicit [x, y, z] point. Use rayCast() if you need to retrieve the hit point

Parameters:

  • other (KX_GameObject or 3-tuple) – [x, y, z] or object towards which the ray is casted

  • dist (float) – max distance to look (can be negative => look behind); 0 or omitted => detect up to other

  • prop (string) – property name that object must have; can be omitted => detect any object

Returns:

the first object hit or None if no object or object does not match prop

Return type:

KX_GameObject

rayCast(objto, objfrom=None, dist=0, prop='', face=False, xray=False, poly=0, mask=0xFFFF)

Look from a point/object to another point/object and find first object hit within dist that matches prop. if poly is 0, returns a 3-tuple with object reference, hit point and hit normal or (None, None, None) if no hit. if poly is 1, returns a 4-tuple with in addition a KX_PolyProxy as 4th element. if poly is 2, returns a 5-tuple with in addition a 2D vector with the UV mapping of the hit point as 5th element.

# shoot along the axis gun-gunAim (gunAim should be collision-free)
obj, point, normal = gun.rayCast(gunAim, None, 50)
if obj:
   # do something
   pass

The face parameter determines the orientation of the normal.

  • 0 => hit normal is always oriented towards the ray origin (as if you casted the ray from outside)

  • 1 => hit normal is the real face normal (only for mesh object, otherwise face has no effect)

The ray has X-Ray capability if xray parameter is 1, otherwise the first object hit (other than self object) stops the ray. The prop and xray parameters interact as follow.

  • prop off, xray off: return closest hit or no hit if there is no object on the full extend of the ray.

  • prop off, xray on : idem.

  • prop on, xray off: return closest hit if it matches prop, no hit otherwise.

  • prop on, xray on : return closest hit matching prop or no hit if there is no object matching prop on the full extend of the ray.

The KX_PolyProxy 4th element of the return tuple when poly=1 allows to retrieve information on the polygon hit by the ray. If there is no hit or the hit object is not a static mesh, None is returned as 4th element.

The ray ignores collision-free objects and faces that dont have the collision flag enabled, you can however use ghost objects.

Parameters:

  • objto (KX_GameObject or 3-tuple) – [x, y, z] or object to which the ray is casted

  • objfrom (KX_GameObject or 3-tuple or None) – [x, y, z] or object from which the ray is casted; None or omitted => use self object center

  • dist (float) – max distance to look (can be negative => look behind); 0 or omitted => detect up to to

  • prop (string) – property name that object must have; can be omitted or “” => detect any object

  • face (integer) – normal option: 1=>return face normal; 0 or omitted => normal is oriented towards origin

  • xray (integer) – X-ray option: 1=>skip objects that don’t match prop; 0 or omitted => stop on first object

  • poly (integer) –

    polygon option: 0, 1 or 2 to return a 3-, 4- or 5-tuple with information on the face hit.

    • 0 or omitted: return value is a 3-tuple (object, hitpoint, hitnormal) or (None, None, None) if no hit

    • 1: return value is a 4-tuple and the 4th element is a KX_PolyProxy or None if no hit or the object doesn’t use a mesh collision shape.

    • 2: return value is a 5-tuple and the 5th element is a 2-tuple (u, v) with the UV mapping of the hit point or None if no hit, or the object doesn’t use a mesh collision shape, or doesn’t have a UV mapping.

  • mask (integer (bit mask)) – collision mask: The collision mask (16 layers mapped to a 16-bit integer) is combined with each object’s collision group, to hit only a subset of the objects in the scene. Only those objects for which collisionGroup & mask is true can be hit.

Returns:

(object, hitpoint, hitnormal) or (object, hitpoint, hitnormal, polygon) or (object, hitpoint, hitnormal, polygon, hituv).

  • object, hitpoint and hitnormal are None if no hit.

  • polygon is valid only if the object is valid and is a static object, a dynamic object using mesh collision shape or a soft body object, otherwise it is None

  • hituv is valid only if polygon is valid and the object has a UV mapping, otherwise it is None

Return type:

Note

The ray ignores the object on which the method is called. It is casted from/to object center or explicit [x, y, z] points.

  • points, contact point data of the collision or None

Return type:

2-tuple (boolean, list of KX_CollisionContactPoint or None)

setCollisionMargin(margin)

Set the objects collision margin.

Parameters:

margin (float) – the collision margin distance in blender units.

Note

If this object has no physics controller (a physics ID of zero), this function will raise RuntimeError.

sendMessage(subject, body='', to='')

Sends a message.

Parameters:

  • subject (string) – The subject of the message

  • body (string) – The body of the message (optional)

  • to (string) – The name of the object to send the message to (optional)

reinstancePhysicsMesh(gameObject, meshObject, dupli, evaluated)

Updates the physics system with the changed mesh.

If no arguments are given the physics mesh will be re-created from the first mesh assigned to the game object.

Parameters:

  • gameObject (string, KX_GameObject or None) – optional argument, set the physics shape from this gameObjets mesh.

  • meshObject (string, KX_MeshProxy or None) – optional argument, set the physics shape from this mesh.

  • dupli (boolean) – optional argument, duplicate the physics shape.

  • evaluated (boolean) – optional argument, use evaluated object physics shape (Object with modifiers applied).

Returns:

True if reinstance succeeded, False if it failed.

Return type:

boolean

Note

If this object has instances the other instances will be updated too.

Note

The gameObject argument has an advantage that it can convert from a mesh with modifiers applied (such as the Subdivision Surface modifier).

Warning

Only triangle mesh type objects are supported currently (not convex hull)

Warning

If the object is a part of a compound object it will fail (parent or child)

Warning

Rebuilding the physics mesh can be slow, running many times per second will give a performance hit.

Warning

Duplicate the physics mesh can use much more memory, use this option only for duplicated meshes else use replacePhysicsShape().

replacePhysicsShape(gameObject)

Replace the current physics shape.

Parameters:

gameObject (string, KX_GameObject) – set the physics shape from this gameObjets.

Returns:

True if replace succeeded, False if it failed.

Return type:

boolean

Warning

Triangle mesh shapes are not supported.

get(key[, default])

Return the value matching key, or the default value if its not found. :arg key: the matching key :type key: string :arg default: optional default value is the key isn’t matching, defaults to None if no value passed. :return: The key value or a default.

playAction(name, start_frame, end_frame, layer=0, priority=0, blendin=0, play_mode=KX_ACTION_MODE_PLAY, layer_weight=0.0, ipo_flags=0, speed=1.0, blend_mode=KX_ACTION_BLEND_BLEND)

Plays an action.

Parameters:

  • name (string) – the name of the action.

  • start (float) – the start frame of the action.

  • end (float) – the end frame of the action.

  • layer (integer) – the layer the action will play in (actions in different layers are added/blended together).

  • priority (integer) – only play this action if there isn’t an action currently playing in this layer with a higher (lower number) priority.

  • blendin (float) – the amount of blending between this animation and the previous one on this layer.

  • play_mode (integer) – the play mode. one of these constants.

  • layer_weight (float) – how much of the previous layer to use for blending.

  • ipo_flags (integer (bit mask)) – flags for the old IPO behaviors (force, etc).

  • speed (float) – the playback speed of the action as a factor (1.0 = normal speed, 2.0 = 2x speed, etc).

  • blend_mode (integer) – how to blend this layer with previous layers. one of these constants.

stopAction([layer])

Stop playing the action on the given layer.

Parameters:

layer (integer) – The layer to stop playing, defaults to 0 if no value passed.

getActionFrame([layer])

Gets the current frame of the action playing in the supplied layer.

Parameters:

layer (integer) – The layer that you want to get the frame from, defaults to 0 if no value passed.

Returns:

The current frame of the action

Return type:

float

getActionName([layer])

Gets the name of the current action playing in the supplied layer.

Parameters:

layer (integer) – The layer that you want to get the action name from, defaults to 0 if no value passed.

Returns:

The name of the current action

Return type:

string

setActionFrame(frame[, layer])

Set the current frame of the action playing in the supplied layer.

Parameters:

  • layer (integer) – The layer where you want to set the frame, defaults to 0 if no value passed.

  • frame (float) – The frame to set the action to

isPlayingAction([layer])

Checks to see if there is an action playing in the given layer.

Parameters:

layer (integer) – The layer to check for a playing action, defaults to 0 if no value passed.

Returns:

Whether or not the action is playing

Return type:

boolean

addDebugProperty(name[, debug])

Adds a single debug property to the debug list.

Parameters:

  • name (string) – name of the property that added to the debug list.

  • debug (boolean) – the debug state, defaults to True if no value passed.
