movingImg

​

Overview

​

Constructor

movingImg(surface, image, pos=vec2d(0,0), speed=vec2d(1,0), gravity=1)

​

Parameters

​

Methods

​

draw()

def draw(self)

1. Checks if image hits horizontal boundaries (left/right edges)
   • Reverses X velocity if collision detected
2. Checks if image hits vertical boundaries (top/bottom edges)
   • Reverses Y velocity if collision detected
3. Updates position by adding speed vector
4. Updates the rect object
5. Blits the image to the surface

​

Attributes

• image - The loaded pygame image surface
• pos - Current position as vec2d
• speed - Velocity vector as vec2d
• size - Image dimensions as vec2d
• rect - The pygame.Rect used for positioning and drawing
• surfaceSize - Size of the surface for boundary detection

​

Usage Example

moveImg = movingImg(screen,
    "images/toggle1.png",
    pos=vec2d(0, SCREEN_HEIGHT*3/4),
    speed=vec2d(5, 0))

# Add to world objects list
world = [button, togglebtn, clockImg, hand, textTest, moveImg, floater, ball]

# In game loop
for obj in world:
    obj.draw()  # Automatically moves and bounces

​

Notes

• The image automatically bounces when it hits any screen edge
• Velocity reversal creates a “bounce” effect
• The gravity parameter is defined but not currently implemented in the movement logic
• Image size is automatically determined from the loaded image
• Position and velocity are updated every frame when draw() is called
• Uses vec2d for 2D vector operations
• Images are loaded without convert_alpha() unlike other image widgets
