direct.controls.GravityWalker

from direct.controls.GravityWalker import GravityWalker

GravityWalker.py is for avatars.

A walker control such as this one provides:

• creation of the collision nodes

• handling the keyboard and mouse input for avatar movement

• moving the avatar

it does not:

• play sounds

• play animations

although it does send messages that allow a listener to play sounds or animations based on walker events.

class GravityWalker(gravity=64.348, standableGround=0.707, hardLandingForce=16.0, legacyLifter=False)

Bases: DirectObject

DiagonalFactor = 0.7071067811865476

__init__(self, gravity=64.348, standableGround=0.707, hardLandingForce=16.0, legacyLifter=False)

addBlastForce(self, vector)

debugPrint(self, message)

for debugging

deleteCollisions(self)

disableAvatarControls(self)

Ignore the arrow keys, etc.

displayDebugInfo(self)

For debug use.

doDeltaPos(self)

earlyEventSphere = 0

enableAvatarControls(self)

Activate the arrow keys, etc.

flushEventHandlers(self)

getAirborneHeight(self)

getCollisionsActive(self)

getGravity(self, gravity)

getIsAirborne(self)

getSpeeds(self)

getVelocity(self)

handleAvatarControls(self, task)

Check on the arrow keys and update the avatar.

initializeCollisions(self, collisionTraverser, avatarNodePath, avatarRadius=1.4, floorOffset=1.0, reach=1.0)

floorOffset is how high the avatar can reach. I.e. if the avatar

walks under a ledge that is <= floorOffset above the ground (a double floor situation), the avatar will step up on to the ledge (instantly).

Set up the avatar collisions

notify = <direct.directnotify.Notifier.Notifier object>

oneTimeCollide(self)

Makes one quick collision pass for the avatar, for instance as a one-time straighten-things-up operation after collisions have been disabled.

placeOnFloor(self)

Make a reasonable effor to place the avatar on the ground. For example, this is useful when switching away from the current walker.

reset(self)

setAirborneHeightFunc(self, unused_parameter)

setAvatar(self, avatar)

setAvatarPhysicsIndicator(self, indicator)

indicator is a NodePath

setCollisionRayHeight(self, height)

setCollisionsActive(self, active=1)

setFloorBitMask(self, bitMask)

setGravity(self, gravity)

setMayJump(self, task)

This function’s use is internal to this class (maybe I’ll add the __ someday). Anyway, if you want to enable or disable jumping in a general way see the ControlManager (don’t use this).

setPriorParentVector(self)

setTag(self, key, value)

setWalkSpeed(self, forward, jump, reverse, rotate)

setWallBitMask(self, bitMask)

setupEventSphere(self, bitmask, avatarRadius)

Set up the collision sphere

setupFloorSphere(self, bitmask, avatarRadius)

Set up the collision sphere

setupRay(self, bitmask, floorOffset, reach)

setupWallSphere(self, bitmask, avatarRadius)

Set up the collision sphere

startJumpDelay(self, delay)

swapFloorBitMask(self, oldMask, newMask)

wantDebugIndicator = 0
