This code allows you to add smooth movement and scaling to pygame surfaces. Mostly all the animation types require a duration (in seconds) and a function (if you dont want to use the default function).
-
python3
-
pygame 1.9.5
-
easings.py
-
Animations.py
This animation runs indefinitely and adds a floating effect to the surface.
__init__(surface_rectangle , magnitude , axis , duration , function = inOutCubic)
-
magnitudeis the number of pixels the surface travels on the screen. -
axisis either"x"or"y". -
durationis always in seconds. Its the time taken to complete once cycle. -
functionis the easing-function imported from easings.py and set to default asinOutCubic
Float.start_float()
- It returns a new value according to the
axispassed and it must assigned tosurface_rect.xorsurface_rect.yin the main pygame loop.

Screen.blit(surface, surface_rect)
pygame.display.update()
fps.tick(frames)This animation moves the surface to a desired position.
__init__(surface_rectangle , duration , function = inOutCubic)
-
durationis the time taken to move the surface from its old position to thenew_position. -
functionis the easing-function imported from easings.py and set to default asinOutCubic.
Move.moveto(new_position)
-
new_positionmust be a list having[new_xpos , new_ypos]. -
The function must be called inside the main loop.

fps.tick(frames)This animation scales the surface to a new [height , width].
It can be more or less than the original size.
__init__(surface , new_size , duration , function = inOutCubic)
-
new_sizemust be a list/tuple having newheight , width -
durationis the time taken to scale the the surface to itsnew_size -
functionis the easing-function imported from easings.py and set to default asinOutCubic.
SmoothScale.give_surface()
- It must be called in the main loop.
- It returns a new surface with
new_size

fps.tick(frames)This animation allows you to change color slowly , reverse it and repeat it.
__init__(starting_color , ending_color , rate , reverse = False , repeat = False)
-
starting_coloris the initial color/ the color you want to start with. -
ending_coloris the final color which will be returned. -
Both the colors must be either in
R,G,Bformat. -
rateis directly proportional to the time taken to complete 1 cycle of this animation. It must be +ve value.
Colorshift.changecolor()
- It must be called in the main loop
- It returns a new color.

This generates particles at the position passed in.
__init__(render_surface)
render_surfaceis the surface you want to generate the particles on.
Particles.append_particles(position , velocity , radius , color , rate)
positionis thex,ycoordinates for a particle.velocityis the direction and speed at which the particles are headed.radiusdefines the size of the particle.coloris the color for the particlesratedefines how fast or slow the particles disappear- The function must be called in the main loop
Particles.make_particles()
- Blits the particles onto the screen
- The function must be called in the main loop
