Hi I am just a beginner and I am trying to make a Ferris wheel animation.
I was able to deduce where the window started crashing and it is the block of code below.
def carriages(cx1,cy1,cx2,cy2,cx3,cy3,cx4,cy4,cx5,cy5,cx6,cy6,cx7,cy7,cx8,cy8,cx9,cy9,cx10,cy10,cx11,cy11,cx12,cy12,cx13,cy13,cx14,cy14,cx15,cy15):#gather variables for placement
carriage1 = pygame.draw.polygon(screen, yellow, [[-30+cx1,-10+cy1],[30+cx1,-10+cy1],[20+cx1,10+cy1],[-20+cx1,10+cy1]],0)#the four points of the carriages with center at 0 plus the positions they need to be placed on ferris
carriage2 = pygame.draw.polygon(screen, yellow, [[-30+cx2,-10+cy2],[30+cx2,-10+cy2],[20+cx2,10+cy2],[-20+cx2,10+cy2]],0)
carriage3 = pygame.draw.polygon(screen, yellow, [[-30+cx3,-10+cy3],[30+cx3,-10+cy3],[20+cx3,10+cy3],[-20+cx3,10+cy3]],0)
carriage4 = pygame.draw.polygon(screen, yellow, [[-30+cx4,-10+cy4],[30+cx4,-10+cy4],[20+cx4,10+cy4],[-20+cx4,10+cy4]],0)
carriage5 = pygame.draw.polygon(screen, yellow, [[-30+cx5,-10+cy5],[30+cx5,-10+cy5],[20+cx5,10+cy5],[-20+cx5,10+cy5]],0)
carriage6 = pygame.draw.polygon(screen, yellow, [[-30+cx6,-10+cy6],[30+cx6,-10+cy6],[20+cx6,10+cy6],[-20+cx6,10+cy6]],0)
carriage7 = pygame.draw.polygon(screen, yellow, [[-30+cx7,-10+cy7],[30+cx7,-10+cy7],[20+cx7,10+cy7],[-20+cx7,10+cy7]],0)
carriage8 = pygame.draw.polygon(screen, yellow, [[-30+cx8,-10+cy8],[30+cx8,-10+cy8],[20+cx8,10+cy8],[-20+cx8,10+cy8]],0)
carriage9 = pygame.draw.polygon(screen, yellow, [[-30+cx9,-10+cy9],[30+cx9,-10+cy9],[20+cx9,10+cy9],[-20+cx9,10+cy9]],0)
carriage10 = pygame.draw.polygon(screen, yellow, [[-30+cx10,-10+cy10],[30+cx10,-10+cy10],[20+cx10,10+cy10],[-20+cx10,10+cy10]],0)
carriage11 = pygame.draw.polygon(screen, yellow, [[-30+cx11,-10+cy11],[30+cx11,-10+cy11],[20+cx11,10+cy11],[-20+cx11,10+cy11]],0)
carriage12 = pygame.draw.polygon(screen, yellow, [[-30+cx12,-10+cy12],[30+cx12,-10+cy12],[20+cx12,10+cy12],[-20+cx12,10+cy12]],0)
carriage13 = pygame.draw.polygon(screen, yellow, [[-30+cx13,-10+cy13],[30+cx13,-10+cy13],[20+cx13,10+cy13],[-20+cx13,10+cy13]],0)
carriage14 = pygame.draw.polygon(screen, yellow, [[-30+cx14,-10+cy14],[30+cx14,-10+cy14],[20+cx14,10+cy14],[-20+cx14,10+cy14]],0)
carriage15 = pygame.draw.polygon(screen, yellow, [[-30+cx15,-10+cy15],[30+cx15,-10+cy15],[20+cx15,10+cy15],[-20+cx15,10+cy15]],0)
In this code, the 15 carriages are draw with their centre at 0. The cx and cy values then move the carriage to the right position on the ferris wheel. Each carriage has their own value because they each have their own spot on the ferris wheel.
I did try changing the value to global but it didn't change anything.
I have made sure that the call function is in the right place.
No error message appears before, during or after the window crashes.
Thank you for looking at this question and it would be greatly appreciated if you can help me out.
Here is the rest of my code due to the code above not being the problem. (I know it is a bit unorganized but I am still making it)
