Converting PyGame 2 axis joystick float to 360 angle

Click For Summary
SUMMARY

The discussion focuses on converting joystick axis floats from PyGame into a 360-degree angle for player direction control in games. The primary method identified is the use of the Atan2 function, which takes horizontal and vertical axis values as inputs. The variables involved include 'self.rot', 'horaxis', and 'veraxis', which correspond to the joystick's rotation and axis values. The issue was resolved through additional research and community input, confirming the effectiveness of Atan2 for this purpose.

PREREQUISITES
  • Understanding of PyGame 2.0 joystick input handling
  • Familiarity with trigonometric functions, specifically Atan2
  • Basic programming skills in Python
  • Knowledge of game development concepts related to player direction
NEXT STEPS
  • Implement joystick input handling in PyGame 2.0
  • Explore the Atan2 function in Python for angle calculations
  • Research additional joystick calibration techniques
  • Learn about player movement mechanics in game development
USEFUL FOR

Game developers, particularly those working with PyGame, and programmers looking to implement joystick controls and player direction mechanics in their projects.

I would like to convert my joystick's two axis float (horizontal and vertical) to a 360 angle that can be used to set a players direction in my game. From my research, I've found the best route to take is using Atan2.

Variables:
Code:
self.rot = 0
horaxis = joy1.get_axis(0)
veraxis = joy1.get_axis(1)

Demonstration Diagram: you are correct, it is drawn in MS Paint

Absolutely any suggestions/snippets for the code would be amazing!

So what is unclear? The atan2 function gets the x and y displacement as input, you have both.
The center could be checked with an additional if condition.

Managed to solve the issue doing some extra research. Thanks for the reply.
