Code for Avatar control 3rd Person Adventure Game Style
1 Attachment(s)
Example code for controlling a user avatar. Console adventure game style.
Left mouse button rotates view, mouse wheel zooms.
WASD keys move avatar. Spacebar triggers jump. 'V' key triggers attack.
Code:
import viz
import viztask
import vizmat
viz.go()
#avatarRoot = viz.addGroup()
avatarRoot = viz.add('marker.wrl')
cameraLookAtNode = viz.addGroup(parent=avatarRoot, pos=[0, 1.5, 0])
avatar = viz.add('vcc_male.cfg', parent=avatarRoot)
viz.add('tut_ground.wrl')
def moveAvatar():
while True:
#get user input
newPos = vizmat.Vector()
newPos.set([0,0,0])
if viz.iskeydown('w'):
#walk forward
newPos = newPos + [0, 0, 1]
if viz.iskeydown('s'):
newPos = newPos + [0, 0, -1]
if viz.iskeydown('a'):
newPos = newPos + [-1, 0, 0]
if viz.iskeydown('d'):
newPos = newPos + [1, 0, 0]
isJumping = False
isAttacking = False
if viz.iskeydown(' '):
#jump
isJumping = True
elif viz.iskeydown('v'):
isAttacking = True
if isAttacking:
avatar.state(6)
yield viztask.waitTime( 1.5 )
if newPos.length() > 0 or isJumping:
if newPos.length() == 0:
#jumping but no direction key, use current heading
t = vizmat.Transform()
t.setTrans([0, 0, 1.8])
t.postEuler(avatar.getEuler()[0],0,0)
newPos = vizmat.Vector( t.getTrans() )
newYaw = vizmat.AngleToPoint(0, 0, newPos[0], newPos[2])
avatar.setEuler(newYaw, 0, 0)
if not isJumping:
#just walking
cameraEuler = viz.MainView.getEuler()
avatarRoot.setEuler(cameraEuler[0], 0, 0)
newPos = newPos * viz.getFrameElapsed()
avatarRoot.setPosition(newPos, viz.REL_LOCAL)
avatar.state(2)
else:
#jumping
avatar.state(7)
yield viztask.waitTime( avatar.getDuration(7)+.01 )
#compute jump direction
newJumpPos = vizmat.Transform()
newJumpPos.setTrans([0, 0, 1.8])
newJumpPos.postEuler(avatar.getEuler(viz.ABS_GLOBAL)[0], 0, 0)
avatarRoot.setPosition(newJumpPos.getTrans(), viz.REL_GLOBAL)
if not (viz.iskeydown(' ') or viz.iskeydown('w') or viz.iskeydown('s') or viz.iskeydown('a') or viz.iskeydown('d') ):
avatar.state(1)
yield None
viztask.schedule(moveAvatar())
import vizcam
camera = vizcam.PivotNavigate()
camera.setDistance(5)
def moveCamera():
while True:
lookAtPos = avatar.getBone('Bip01 Pelvis').getPosition(viz.ABS_GLOBAL)
lookAtPos[1] = lookAtPos[1] + .5
camera.setCenter(lookAtPos)
camera.updateCenter()
yield None
viztask.schedule(moveCamera())
