problem with exam task for college
hy everyone, for my exam this year i had to write a computer game on vpython (visualpython).we had to make a lunar lander game where the ship drops by gravity and is able to manouver to safely land on the moon.right now i am completely stuck on trying to make the visual of the ship rotate.i'm new to this forum, i guess i'll just paste my code here. Everything works fine on the game, except the rotation of the ship. however the when you press "up" the after rotating the velocity actually changes direction , but the visual doesn't. i'm getting kinda nervous because due date is coming, any help is appreciated, here is the code: from visual import * import time import math import random from datetime import datetime import operator class lunar_lander(object): def __init__(self): scene.title = 'mini star wars' scene.width = 375 scene.height = 550 scene.center = (0,0) self.pos = (0,0) self.axis = 0 self.brandstofmeter = brandstofmeter() self.ruimteschip = ruimteschip() self.view = game_view(self) def play(self): t=0 dt=0.01 while t<9: time.sleep(0.01) self.brandstofmeter.update self.ruimteschip.update(dt) t = t + dt class game_view(object): def __init__(self,owner): autoscale=True box(pos=( 0, -375, 0), length=500, height=5, width=0, color = color.white) box(pos=(0,375, 0), length=500, height=5, width=0, color = color.white) box(pos=(-250,0, 0), length=5, height=750, width=0, color = color.white) box(pos=(250,0, 0), length=5, height=750, width=0, color = color.white) maan = curve(pos=[(-250,-353),(-240,-341),(-210,-354),(-199.5,-374)],color=color.red) maana = curve(pos=[(-199.5,-374),(-166,-374)],color=color.green) maanb = curve(pos=[(-166,-374),(-140,-357),(-80,-319),(-40,-361),(0,-321),(40,-329),(80,-347)],color=color.red) maanc = curve(pos=[(80,-347),(140,-347)],color=color.green) maand = curve(pos=[(140,-347),(162,-337),(189.5,-365),(210,-355),(240,-372),(250,-338)],color=color.red) for i in random.sample(range (-250,250),20): for j in random.sample(range (-375,375),20): sterren = points(pos = [i,j,0],size = 2, color=color.white) class brandstofmeter(object): def __init__(self): self.size = (25,45) axis = 0 self.pos = (220,345) self.view = brandstofmeter_view(self) def update(self): while True: if scene.kb.keys: s = scene.kb.getkey() if (s == 'up'): self.view.update(self) class brandstofmeter_view(object): def __init__(self,owner): self.owner = owner meter = box(pos = owner.pos,size = owner.size,color = color.green) def update (self,owner): self.size = self.size - (0,0.45) class ruimteschip(object): def __init__(self): self.pos = vector(0,330) self.acceleration = vector(0,-88,0) self.axis = (1,0,0) self.hoek = (90*math.pi)/180 self.graden = math.degrees(self.hoek) self.gas = vector(10 * cos(self.hoek),10 * sin (self.hoek)) self.velocity = vector(0,0,0) self.angle = (1,0,0) self.view = ruimteschip_view(self) self.vlam = self.view.vlam self.frame = self.view.frame def update(self,dt): self.velocity = self.velocity + (self.acceleration * dt) self.pos = self.pos + self.velocity * dt a = 0 b = 0 if scene.kb.keys: a = a + 0.001 s = scene.kb.getkey() if (s == "up"): self.velocity = self.velocity + self.gas self.vlam.visible = True b = b + 2 if (s == "left"): self.gas = rotate(self.gas,angle = math.pi/10, axis = (0,0,1)) c = list(self.frame.axis) c[2] -= 0.1 c = tuple(c) c = self.frame.axis if (s == "right") : self.gas = rotate(self.gas,angle = -(math.pi/10), axis = (0,0,1)) c = list(self.frame.axis) c[2] += 0.1 c = tuple(c) c = self.frame.axis if (a == 0): self.vlam.visible = False if self.pos.x > 250: self.pos.x = -250 if self.pos.x < -250: self.pos.x = 250 self.view.update(self) class ruimteschip_view(object): def __init__(self,owner): self.owner = owner self.frame = frame(pos = owner.pos,axis
Re: problem with exam task for college
woow jeezes, thanks for the amazingly fast and detailed response, you guys are amazing. let's clear a few things up : 1) points is a module in vpython to make points, the points do in fact appear although its not really the effect i intended to have, the points are "lined up" in stead of randomly separated, if you know what i mean 2) sorry for the dutch names :) 3) i put the parenteces there and then i got a bunch of errors which i fixed 2 problems: a) my program seems to be stuck in the update phase of brandstoftank(=fuel tank), it doesnt get to the update of the spaceship b) the problem i originally described in my first post was not resolved, by means of elimination i could conclude that the problem situates itself in this lines : if (s == "left"): self.gas = rotate(self.gas,angle = math.pi/10, axis = (0,0,1)) c = list(self.frame.axis) c[2] -= 0.1 c = tuple(c) c = self.frame.axis if (s == "right") : self.gas = rotate(self.gas,angle = -(math.pi/10), axis = (0,0,1)) c = list(self.frame.axis) c[2] += 0.1 c = tuple(c) c = self.frame.axis i will put the full revisited code here : from visual import * import time import math import random from datetime import datetime import operator class lunar_lander(object): def __init__(self): scene.title = 'mini star wars' scene.width = 375 scene.height = 550 scene.center = (0,0) self.pos = (0,0) self.axis = 0 self.brandstofmeter_view = brandstofmeter_view() self.ruimteschip = ruimteschip() self.view = game_view(self) def play(self): t=0 dt=0.01 while t<9: time.sleep(0.01) self.brandstofmeter_view.update() self.ruimteschip.update(dt) t = t + dt class game_view(object): def __init__(self,owner): autoscale=True box(pos=( 0, -375, 0), length=500, height=5, width=0, color = color.white) box(pos=(0,375, 0), length=500, height=5, width=0, color = color.white) box(pos=(-250,0, 0), length=5, height=750, width=0, color = color.white) box(pos=(250,0, 0), length=5, height=750, width=0, color = color.white) maan = curve(pos=[(-250,-353),(-240,-341),(-210,-354),(-199.5,-374)],color=color.red) maana = curve(pos=[(-199.5,-374),(-166,-374)],color=color.green) maanb = curve(pos=[(-166,-374),(-140,-357),(-80,-319),(-40,-361),(0,-321),(40,-329),(80,-347)],color=color.red) maanc = curve(pos=[(80,-347),(140,-347)],color=color.green) maand = curve(pos=[(140,-347),(162,-337),(189.5,-365),(210,-355),(240,-372),(250,-338)],color=color.red) for i in random.sample(range (-250,250),20): for j in random.sample(range (-375,375),20): sterren = points(pos = [i,j,0],size = 2, color=color.white) class brandstofmeter_view(object): def __init__(self): axis = 0 self.pos = (220,345) self.meter = box(pos = self.pos, lenght = 25, height = 45,color = color.green) def update (self): s = scene.kb.getkey() if (s == "up"): self.meter.height = self.meter.height - 1 class ruimteschip(object): def __init__(self): self.pos = vector(0,330) self.acceleration = vector(0,-88,0) self.axis = (1,0,0) self.hoek = (90*math.pi)/180 self.graden = math.degrees(self.hoek) self.gas = vector(10 * cos(self.hoek),10 * sin (self.hoek)) self.velocity = vector(0,0,0) self.angle = (1,0,0) self.view = ruimteschip_view(self) self.vlam = self.view.vlam self.frame = self.view.frame def update(self,dt): self.velocity = self.velocity + (self.acceleration * dt) self.pos = self.pos + self.velocity * dt a = 0 b = 0 if scene.kb.keys: a = a + 0.001 s = scene.kb.getkey() if (s == "up"): self.velocity = self.velocity + self.gas self.vlam.visible = True b = b + 2 if (s == "left"): self.gas = rotate(self.gas,angle = math.pi/10, axis = (0,0,1)) c = list(self.frame.axis) c[2] -= 0.1 c = tuple(c) c = self.frame.axis if (s == "right") : self.gas = rotate(self.gas,angle = -(math.pi/10), axis = (0,0,1)) c = list(self.frame.axis) c[2] += 0.1 c = tuple(c) c = self.frame.axis if (a == 0): self.vlam.visible = Fals

Re: problem with exam task for college
ok after another round of reparations, my update works again and it updates the fuel meter, but i still can't get the view of the spaceship to rotate, for now only the direction the spaceship accelerates when pressing "up" changes after a rotation, but the spaceship itself keeps pointing up.

this is what i have right now, it tells me i can't multiply a vector with a vector, i have to find a way to multiply the speed with the updated angle (=hoek in dutch) code : from visual import * import time import math import random class lunar_lander(object): def __init__(self): scene.title = 'mini star wars' scene.width = 375 scene.height = 550 scene.center = (0,0) self.pos = (0,0) self.axis = 0 self.brandstofmeter = brandstofmeter() self.ruimteschip = ruimteschip() self.view = game_view(self) def play(self): t=0 dt=0.01 while t<9: time.sleep(0.01) self.brandstofmeter.update self.ruimteschip.update(dt) t = t + dt class game_view(object): def __init__(self,owner): autoscale=True box(pos=( 0, -375, 0), length=500, height=5, width=0, color = color.white) box(pos=(0,375, 0), length=500, height=5, width=0, color = color.white) box(pos=(-250,0, 0), length=5, height=750, width=0, color = color.white) box(pos=(250,0, 0), length=5, height=750, width=0, color = color.white) maan = curve(pos=[(-250,-353),(-240,-341),(-210,-354),(-199.5,-374)],color=color.red) maana = curve(pos=[(-199.5,-374),(-166,-374)],color=color.green) maanb = curve(pos=[(-166,-374),(-140,-357),(-80,-319),(-40,-361),(0,-321),(40,-329),(80,-347)],color=color.red) maanc = curve(pos=[(80,-347),(140,-347)],color=color.green) maand = curve(pos=[(140,-347),(162,-337),(189.5,-365),(210,-355),(240,-372),(250,-338)],color=color.red) for i in random.sample(range (-250,250),20): for j in random.sample(range (-375,375),20): sterren = points(pos = [i,j,0],size = 2, color=color.white) class brandstofmeter(object): def __init__(self): self.size = (25,45) axis = 0 self.pos = (220,345) self.view = brandstofmeter_view(self) def update(self): while True: if scene.kb.keys: s = scene.kb.getkey() if (s == 'up'): self.view.update(self) class brandstofmeter_view(object): def __init__(self,owner): self.owner = owner meter = box(pos = owner.pos,size = owner.size,color = color.green) def update (self,owner): self.size = self.size - (0,0.45) class ruimteschip(object): def __init__(self): self.pos = vector(0,330) self.axis = (1,0,0) self.view = ruimteschip_view(self) self.vlam = self.view.vlam self.frame = self.view.frame self.hoek = pi / 2 def update(self,dt): zwaartekracht = vector(0,-2,0) self.gas = vector(0,10,0) self.acceleration = zwaartekracht self.axis = (1,0,0) if scene.kb.keys: s = scene.kb.getkey() if (s == "up"): self.acceleration =+ self.gas * vector(math.cos(self.hoek),math.sin(self.hoek)) if (s == "left"): self.hoek =+ pi/12 if (s == "right") : self.hoek =- pi/12 self.pos = self.pos + self.acceleration if self.pos.x > 250: self.pos.x = -250 if self.pos.x < -250: self.pos.x = 250 if self.acceleration != (0,-2,0): self.vlam.visible = True else : self.vlam.visible = False self.view.update(self) class ruimteschip_view(object): def __init__(self,owner): self.owner = owner self.frame = frame(pos = owner.pos,axis = owner.axis) self.motor = curve(frame = self.frame,pos=[(0,24.0),(22.0,24.0),(22.0,39.0),(-22.0,39.0),(-22,24),(0,24)]) self.capsule = curve(frame = self.frame,color = color.blue ,pos=[(0,39),(-3,39),(-9,44),(-12,46),(-18,48),(-22,50),(-18,52),(-12,54),(-9,56),(-3,61),(0,61),(3,59),(9,56),(12,54),(18,52),(22,50),(18,48),(12,46),(9,44),(3,39),(0,39)]) self.poota = curve(frame = self.frame,pos = [(-18,24),(-20,24),(-20,0),(-18,0),(-18,24)]) self.pootb = curve(frame = self.frame,pos = [(18,24),(20,24),(20,0),(18,0),(18,24)]) self.vlam = curve(frame = self.frame,color = color.orange , visible=false,pos = [(0,24.0),(-9.0,14.0),(0,-5.0),(9,14.0),(0,24.0)]) def update(self,owner): self.frame.axis = owner.axis self.frame.pos = owner.pos -- http://mail.python.org/mailman/listinfo/python-list
