			standableGround = 0.707,
			hardLandingForce = 16.0 )

Member Function Documentation

addBlastForce()

addBlastForce	(		self,
			vector )

avatarPhysicsIndicator()

avatarPhysicsIndicator	(		self,
			task )

debugPrint()

debugPrint	(		self,
			message )

for debugging

deleteCollisions()

deleteCollisions

(

self

)

determineHeight()

determineHeight

(

self

)

returns the height of the avatar above the ground.
If there is no floor below the avatar, 0.0 is returned.
aka get airborne height.

disableAvatarControls()

disableAvatarControls

(

self

)

Ignore the arrow keys, etc.

displayDebugInfo()

displayDebugInfo

(

self

)

For debug use.

doDeltaPos()

doDeltaPos

(

self

)

enableAvatarControls

(

self

)

Activate the arrow keys, etc.

getVelocity

(

self

)

handleAvatarControls()

handleAvatarControls	(		self,
			task )

Check on the arrow keys and update the avatar.

initializeCollisions()

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

Set up the avatar collisions

oneTimeCollide()

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()

placeOnFloor

(

self

)

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

reset()
