Semi-circle array containing target and distractor objects
Hi,
I wonder if someone can help me, I am trying to set up a semi-circle array of positions on the left hand side of the screen, depending on how many distractors are selected (e.g. either 2, 4, 6 or 8) each position should contain one target object and the rest distractors, these should be randomised. I then want the target position to be a hotspot. But at this stage I'm having trouble just getting an array of positions where I want them with the correct objects in them. Any help would be hugely appreciated. Thank you. Code:
import viz import viztask import random viz.go() Z_dist = -5 #viz.move(0,0,Z_dist) viz.MainView.move(0.5,0,-10) # Add distractor and target objects ballsize = [2.0,2.0,2.0,1.0,1.0,1.0] # Distractor ball distractor = viz.add('soccerball.ive') distractor.setScale(ballsize[0],ballsize[1],2) distractor.addAction(vizact.spin(0,1,0,100)) # Target Ball target = viz.add('ball.wrl') target.setScale(ballsize[3],ballsize[4],1) target.addAction(vizact.spin(0,1,0,100)) # Set up zones for the objects to appear on the screen choice = ['2', '4', '6', '8'] select = viz.choose('How many distractors?', choice) #make a list with the objects in it objects = [distractor,target] # keep 2 positions in an array pos = [[-1.0,0.0,Z_dist],[-1.0,0.5,Z_dist],[-2.0,1.0,Z_dist],[-1.0,1.5,Z_dist],[-1.0,2.0,Z_dist],[-1.0,2.5,Z_dist],[-1.0,3.0,Z_dist],[-1.0,3.5,Z_dist]] rand_positions = [] def sceneOn(num): global rand_positions positions = [0,1,2,3,4,5,6,7] if select == 0: #set objects to 2 different random positions rand_positions = random.sample(positions,2) objects[0].setPosition(pos[rand_positions[0]]) objects[1].setPosition(pos[rand_positions[1]]) if select == 1: #set objects to 4 different random positions rand_positions = random.sample(positions,4) objects[0].setPosition(pos[rand_positions[0]]) objects[0].setPosition(pos[rand_positions[1]]) objects[0].setPosition(pos[rand_positions[2]]) objects[1].setPosition(pos[rand_positions[3]]) if select == 2: #set objects to 4 different random positions rand_positions = random.sample(positions,6) objects[0].setPosition(pos[rand_positions[0]]) objects[0].setPosition(pos[rand_positions[1]]) objects[0].setPosition(pos[rand_positions[2]]) objects[0].setPosition(pos[rand_positions[3]]) objects[0].setPosition(pos[rand_positions[4]]) objects[1].setPosition(pos[rand_positions[5]]) if select == 3: rand_positions = random.sample(positions,8) objects[0].setPosition(pos[rand_positions[0]]) objects[0].setPosition(pos[rand_positions[1]]) objects[0].setPosition(pos[rand_positions[2]]) objects[0].setPosition(pos[rand_positions[3]]) objects[0].setPosition(pos[rand_positions[4]]) objects[0].setPosition(pos[rand_positions[5]]) objects[0].setPosition(pos[rand_positions[6]]) objects[1].setPosition(pos[rand_positions[7]]) sceneOn(1) |

Your script was only creating 2 object, even when more than 2 distractors were selected. I modified your script to dynamically create the objects based on the number of distractors. I also modified the sceneOn function to be more general in positioning the objects.
I'm still not sure what you mean by placing the objects in a semi-circle. The list of positions you have pretty much places all the objects in a vertical line. Anyway, here's the modified script: Code:
import viz import viztask import random viz.go() Z_dist = -5 #viz.move(0,0,Z_dist) viz.MainView.move(0.5,0,-10) # Add distractor and target objects ballsize = [2.0,2.0,2.0,1.0,1.0,1.0] # Set up zones for the objects to appear on the screen choice = ['2', '4', '6', '8'] select = viz.choose('How many distractors?', choice) numDistractors = int(choice[select]) #make a list with the objects in it objects = [] # Distractor ball for x in range(numDistractors-1): distractor = viz.add('soccerball.ive') distractor.setScale(ballsize[0],ballsize[1],2) distractor.addAction(vizact.spin(0,1,0,100)) objects.append(distractor) # Target Ball target = viz.add('ball.wrl') target.setScale(ballsize[3],ballsize[4],1) target.addAction(vizact.spin(0,1,0,100)) objects.append(target) # keep 2 positions in an array pos = [[-1.0,0.0,Z_dist],[-1.0,0.5,Z_dist],[-2.0,1.0,Z_dist],[-1.0,1.5,Z_dist],[-1.0,2.0,Z_dist],[-1.0,2.5,Z_dist],[-1.0,3.0,Z_dist],[-1.0,3.5,Z_dist]] def sceneOn(num): # Get random sample of positions rand_positions = random.sample(pos,numDistractors) # Apply positions to objects for p,o in zip(rand_positions,objects): o.setPosition(p) sceneOn(1) |

Thanks very much for your reply. I have been working hard on this code and it is now completely different from when I posted my initial question. Please see below.
I am having some problems which I would really appreciate help with: 1. how do I stop the avatar going out of the screen? 2. when the avatar's right arm hits the target, I want the avatar to do something e.g. dance, if the avatars right arm hits a distractor then it should something else, e.g. ball should change colour - I have tried setting this up using collisions and hotspots and can't get either to work? 3. I still haven't managed to get the objects in a semi-circle so that they are all equidistant from the avatar start position Any help would be huegly appreciated. Sorry the code is such a mess, any help with tidying it up would also be greatly appreciated. Thank you. Code:

Sorry, forgot to mention there is also a ball in position 0,0 which I can't seem to get rid of.
Thanks again. |
