Handle Mouse Clicks
Now to handle mouse clicks we are going to create a new function called “on_mouse_press”. This function will be called every time user clicks a mouse button.
Python3
# Importing arcade module import arcade # Creating MainGame class class MainGame(arcade.Window): def __init__(self): super().__init__(600, 600, title="Keyboard Inputs") # Starting location of player self.x = 100 self.y = 100 # Creating on_draw() function to draw on the screen def on_draw(self): arcade.start_render() # Drawing our player arcade.draw_circle_filled(self.x, self.y,25, arcade.color.GREEN ) # Creating function to check the position # of the mouse def on_mouse_motion(self, x, y, dx, dy): """ Called whenever the mouse moves. """ self.x = x self.y = y # Creating function to check the mouse clicks def on_mouse_press(self, x, y, button, modifiers): print("Mouse button is pressed") # Calling MainGame class MainGame() arcade.run() |
Output:
Python Arcade – Handling Mouse Inputs
In this article, we will learn how we can handle mouse inputs in the arcade module in Python.
In Arcade, you can easily handle the mouse inputs using these functions:
on_mouse_motion():
Syntax: on_mouse_motion(x, y, dx, dy)
Parameters:
- x : x coordinate
- y : y coordinate
- dx : change in x coordinate
- dy : change in y coordinate
on_mouse_press():
Syntax : on_mouse_press( x, y, button, modifiers)
Parameters:
- x : x coordinate
- y : y coordinate
- button : button that is pressed
- modifiers : Bitwise ‘and’ of all modifiers (shift, ctrl, num lock) pressed during this event.
on_mouse_motion() function will be called whenever the user moves the mouse. Similarly, on_mouse_press() will be called whenever a user presses a mouse button.
