Using hotspots to enable opening doors

[TrashcanPatrol]

Hi thank you for your response, I've tried what you said but it doesn't work still. Here is what I tried:

import viz
viz.go()

SAFE = 1
UNSAFE = 2
TARGET = 3



CIRCLE_X = -3.5
CIRCLE_Z = 3.4
CIRCLE_RADIUS = 0.5

def handlemyhotspots(id,x,y,z):

	if id == SAFE:
		print 'inside safe zone'
		def mykeyboard(key):
			if key == 'e':
			door.runAction( vizact.spinto(0,1,0, -90, 30.0) )
		viz.clearcolor(1,1,1)
		viz.starthotspot(UNSAFE,viz.RECTANGLE_HOTSPOT_OUT,0,3,2.4,6)

	elif id == UNSAFE:
		print 'outside safe zone'
		viz.clearcolor(0,0,0)
		viz.starthotspot(SAFE,viz.RECTANGLE_HOTSPOT_IN,0,3,2.4,6)

	elif id == TARGET:
		print 'at target'

viz.callback(viz.HOTSPOT_EVENT, handlemyhotspots)
viz.starthotspot(UNSAFE,viz.RECTANGLE_HOTSPOT_OUT,0,3,2.4,6)
viz.starthotspot(TARGET,viz.CIRCLE_HOTSPOT_IN,CIRCLE_X,CIRCLE_Z,CIRCLE_RADIUS) 

import math
viz.startlayer(viz.LINES)
viz.linewidth(3)
viz.vertexcolor(viz.RED)
viz.vertex(CIRCLE_X,0,CIRCLE_Z)
viz.vertex(CIRCLE_X,2,CIRCLE_Z)
viz.startlayer(viz.LINE_LOOP)
for a in range(0,360,10):
	x = math.sin(viz.radians(a))*CIRCLE_RADIUS
	z = math.cos(viz.radians(a))*CIRCLE_RADIUS
	viz.vertex(x+CIRCLE_X,0.1,z+CIRCLE_Z)
viz.endlayer()


room=viz.add('room.wrl')
viz.collision(viz.ON)
door = room.getchild('door-FACES')
import vizcam
vizcam.FlyNavigate()

def mykeyboard(key):
  if key == 'e' and id == SAFE:
    door.runAction( vizact.spinto(0,1,0, -90, 30.0) )

--but it doesn't let me open the door like that though. The boldened part I know won't work [and it's not in my code that I was just using] but that's what I'm trying to do with it, it's hard to describe using two definitions with words though.
What do you think I should do for that?

There are two problems with your code. First your mykeyboard function should not be inside of you handlemyhotspots function. You also need a viz.callback line. Try the following code.
Once you enter the safe zone the variable openDoor will be set to true. When you leave the safe zone openDoor is set to false. When you press a key the onKeyDown function will be called. If openDoor is true and the keypressed is 'e' you will be able to open the door.

import viz
viz.go()

viz.MainView.setPosition(0,1.8,-5)

SAFE = 1
UNSAFE = 2
TARGET = 3

viz.add('tut_ground.wrl')

CIRCLE_X = 0
CIRCLE_Z = 3
CIRCLE_RADIUS = 0.5

openDoor = False

def handlemyhotspots(id,x,y,z):
	global openDoor

	if id == SAFE:
		print 'inside safe zone'
		openDoor = True
		viz.clearcolor(1,1,1)
		viz.starthotspot(UNSAFE,viz.RECTANGLE_HOTSPOT_OUT,0,3,2.4,6)

	elif id == UNSAFE:
		print 'outside safe zone'
		openDoor = False
		viz.clearcolor(0,0,0)
		viz.starthotspot(SAFE,viz.RECTANGLE_HOTSPOT_IN,0,3,2.4,6)

	elif id == TARGET:
		print 'at target'

viz.callback(viz.HOTSPOT_EVENT, handlemyhotspots)
viz.starthotspot(UNSAFE,viz.RECTANGLE_HOTSPOT_OUT,0,3,2.4,6)
viz.starthotspot(TARGET,viz.CIRCLE_HOTSPOT_IN,CIRCLE_X,CIRCLE_Z,CIRCLE_RADIUS) 

import math
viz.startlayer(viz.LINES)
viz.linewidth(3)
viz.vertexcolor(viz.RED)
viz.vertex(CIRCLE_X,0,CIRCLE_Z)
viz.vertex(CIRCLE_X,2,CIRCLE_Z)
viz.startlayer(viz.LINE_LOOP)
for a in range(0,360,10):
	x = math.sin(viz.radians(a))*CIRCLE_RADIUS
	z = math.cos(viz.radians(a))*CIRCLE_RADIUS
	viz.vertex(x+CIRCLE_X,0.1,z+CIRCLE_Z)
viz.endlayer()


def onKeyDown(key):
	if key == 'e' and openDoor == True:
		print "open the door"

viz.callback(viz.KEYDOWN_EVENT,onKeyDown)

It worked like a charm, thanks!

...Do you know of a way that one can bind an avatar to the viewpoint, and use the door in a way where, the user presses 'e' and sees the avatar's hand opening the door? If not, that's okay, this will do perfectly.

[Jeff]

You can link the viewpoint to the avatar and manipulate the arm bone so it moves to the doorknob. Here's an example using a link with an offset so the viewpoint is behind the avatar. When the avatar stops moving he raises his arm.

import viz

viz.go()

viz.add('court.ive')

avatar = viz.add('vcc_male.cfg')

link = viz.link(avatar, viz.MainView)
link.preTrans([0,0,-2])

walk = vizact.walkTo([0,0,5])
armup = vizact.boneSpinTo('Bip01 R UpperArm', euler = [0,0,-75], speed = 45)

avatar.addAction(walk)
avatar.addAction(armup)
