Object activity culling

Object activity such as physics or logic can be suspended depending on the distance between the object and the closest camera thanks to UI options:

true

These options determine what kind of culling to proceed and the distance to cull. They are also found in python API under names:

KX_GameObject.logicCulling
KX_GameObject.physicsCulling
KX_GameObject.logicCullingRadius
KX_GameObject.physicsCullingRadius

Also the user can choose which camera are implied in distance computing or choose if a scene enable activity culling. These option as the previous ones are both in UI and python:

true

true

KX_Camera.activityCulling
KX_Scene.activityCulling

Object collision test

It's now possible to test if two objects are colliding without skim all the collisions of an object through a callback. To do so the user have to call the function:

KX_GameObject.collide(otherObject)

This function return a pair tuple, if no collision happened between the objects, the pair is (False, None), else the first element of the pair is True and the second a KX_CollisionContactPoint similar to the one passed to collision callback function.

Camera custom viewport UI

The user is able to specify a custom viewport for camera using a subset of the full viewport. This viewport is specified thanks to ratio of left, right, top and bottom edge of the full viewport. The UI in camera panel is presented as follow:

true

Example of two cameras defining a custom viewport in UI:

true

See also: #a09bc02

Character max slope

Character max slope is used to limit character motion when the slope of the ground is greater than a specific angle specified in the UI physics panel:

true

This value can also be set in python thanks to:

KX_CharacterWrapper.maxSlope

  • Implement python fast keyword parsing. (see #3f9e0b5)
  • Replace SetActiveAction by SetLastFrame in BL_DeformableGameObject. (see #fe84de3)
  • Avoid checking deformer skip transform every frame. (see #5193049)
  • Use memory pool to allocate vertex data. (see #a3e48cc)
  • Implement PyObjectFrom with float array. (see #4326995)
  • Move restrict animation update management in KX_Scene. (see #066db11)
