Touch Controller Problem
Hi I would like to use the touch controller to control the movement of a scooter.
The ideal scene would be each time I load a road scene and the rider starts accelerating then rides the scooter to the end point at a constant speed. However, I am currently encountering two problems: 1) When I start running the script, only part of the scene can be loaded; 2) It seems the touch button events can not be detected as the text 'done' I inserted can not be printed out. Can someone help me out with this pls????? Code:
###### Import packages import viz import sys import vizconnect import vizconfig import vizact import vizshape import viztask import vizinput import vizinfo import time import random import oculus import numpy import steamvr import math from numpy import * hmd = oculus.Rift() touch = hmd.getRightTouchController() viz.go() ##### Parameters viz.setMultiSample(4) viz.fov(60) viz.go() ini_x =6 ini_y = -4.2 ini_z = -145 os_x = 0 os_y = 0 os_z = -5 ground_x =6 ground_y = -4.2 ground_z = -145 v = [15,25,35] a = 4.1667 con = 3 trialNo = 15 trial = v * trialNo ##### Set up mainview viz.MainView.move([ini_x + os_x, ini_y + os_y, ini_z + os_z]) view = viz.MainView # Setup navigation node and link to main view navigationNode = viz.addGroup() viewLink = viz.link(navigationNode, view) viewLink.preMultLinkable(hmd.getSensor()) # Apply user profile eye height to view profile = hmd.getProfile() if profile: navigationNode.setPosition([ground_x,ground_y+profile.eyeHeight,ground_z]) else: navigationNode.setPosition([ground_x,ground_y+1.8,ground_z]) ##### Create skylight viz.MainView.getHeadLight().disable() sky_light = viz.addLight(euler=(0,90,0)) sky_light.position(0,0,-1,0) sky_light.color(viz.WHITE) sky_light.ambient([0.9,0.9,1]) ##### Create sky sky = viz.add(viz.ENVIRONMENT_MAP,'sky.jpg') skybox = viz.add('skydome.dlc') skybox.texture(sky) # Setup Oculus Rift HMD if not hmd.getSensor(): sys.exit('Oculus Rift not detected') # Check if HMD supports position tracking supportPositionTracking = hmd.getSensor().getSrcMask() & viz.LINK_POS if supportPositionTracking: # Add camera bounds model camera_bounds = hmd.addCameraBounds() camera_bounds.visible(False) # Change color of bounds to reflect whether position was tracked def CheckPositionTracked(): if hmd.getSensor().getStatus() & oculus.STATUS_POSITION_TRACKED: camera_bounds.color(viz.GREEN) else: camera_bounds.color(viz.RED) vizact.onupdate(0, CheckPositionTracked) #viz.setMultiSample(8) ### Import the Scooter model scooter = viz.add('G:/ScooterProject/ChengZM/ChengZM_res/scooter.dae') scooter.setPosition([ground_x-0.25,ground_y,ground_z+2.15]) scooter.setEuler([90,0,0]) def UpdateView(m_s,a, up_lim): yaw,pitch,roll = viewLink.getEuler() m = viz.Matrix.euler(yaw,0,0) p = viz.MainView.getPosition() dm = m_s + viz.getFrameElapsed() * a print('m0', m) if dm <= up_lim: ### accelerating if p[0] < (ground_x-0.25)+1.5 and p[0] > (ground_x-0.25)-1.5: print('InIf') if touch.isButtonDown(oculus.BUTTON_INDEX): m.preTrans([0,0,dm]) print('done') if touch.isButtonDown(oculus.BUTTON_HAND): m.preTrans([0,0,-dm]) elif p[0] >= (ground_x-0.25)+1.5 or p[0] <= (ground_x-0.25)-1.5: if touch.isButtonDown(oculus.BUTTON_INDEX): m.preTrans([0,0,dm]) if touch.isButtonDown(oculus.BUTTON_HAND): m.preTrans([0,0,-dm]) else: ### constant speed movement if p[0] < (ground_x-0.25)+1.5 and p[0] > (ground_x-0.25)-1.5: if touch.isButtonDown(oculus.BUTTON_INDEX): m.preTrans([0,0,up_lim]) if touch.isButtonDown(oculus.BUTTON_HAND): m.preTrans([0,0,-up_lim]) elif p[0] >= (ground_x-0.25)+1.5 or p[0] <= (ground_x-0.25)-1.5: if touch.isButtonDown(oculus.BUTTON_INDEX): m.preTrans([0,0,up_lim]) if touch.isButtonDown(oculus.BUTTON_HAND): m.preTrans([0,0,-up_lim]) navigationNode.setPosition(m.getPosition(), viz.REL_PARENT) scooter.setPosition(m.getPosition(), viz.REL_PARENT) return p, dm def sta_timer(): for i in range(3): timer_3D = viz.addText3D(str(i),pos=[ground_x,ground_y+profile.eyeHeight,ground_z+20]) timer_3D.fontSize(10) timer_3D.resolution(1) yield viztask.waitTime(1) timer_3D.visible(viz.OFF) def Sct_dis(): #viz.collision(viz.ON) ##### Experiment starts ##### Randomize trials random.shuffle(trial) for i in range(len(trial)): for j in range(2): yield viz.waitTime(1) ### Import the road model if j == 0: ### the first part in this trial road_model = viz.add('G:/ScooterProject/ChengZM/ChengZM_res/RoadTY-only.dae') ########## should be the reference road road_model.setEuler([90,0,0]) road_model.setPosition([0,-5,-5]) elif j == 1: ### the second part in this trial road_model = viz.add('G:/ScooterProject/ChengZM/ChengZM_res/RoadTY-only.dae') ########## should be the free road road_model.setEuler([90,0,0]) road_model.setPosition([0,-5,-5]) yield viz.waitTime(2) ### Setup arrow key navigation up_lim = trial[i] m_s = 0.01 ### Exp starts sta_timer() final_p = 0 timer1 = vizact.ontimer(0,UpdateView(m_s, a, up_lim)) vizact.ontimer(0,UpdateView(m_s, a, up_lim)) while final_p < 30: startTime = viz.tick() timer1.setEnabled(viz.ON) pp, ss = UpdateView(m_s, a, up_lim) final_p = pp[2] final_s = ss timer1.setEnabled(viz.OFF) yield viz.waitTime(3) ### data record #viz.OFF() viz.quit() viztask.schedule(Sct_dis()) |

Dear tianmoran,
I believe you received support for this question in the WorldViz Ticked Based support system for customers with support contracts, right? Please let us know if this is still an open issue, thanks and all best, Matthias |
