问题描述
我正在将Pygame 1.9.2与Python 3.4配合使用来为机器人创建控制程序.该控制器是通过USB连接的新Xbox One控制器，可以与pygame正常工作.问题在于，触发按钮被视为Axes，根据您按的力度，其值从-1到1.是否可以将其更改为从0到1的范围，或不包含负数的任何其他范围?
I am using Pygame 1.9.2 with Python 3.4 to create a control program for a robot. The controller is a new Xbox One controller connected via USB which is working fine with pygame. The problem is that the trigger buttons are considered Axes which give values from -1 to 1 depending on how hard you press. Is there a way to change this to a range from 0 to 1 or any other range that does not include negative numbers?
谢谢
推荐答案
(x + 1.0) / 2.0其中，x是您从控制器获得的值，应该为0..1(+ 1.0是为了使您获得在0..2)
(x + 1.0) / 2.0 where x is whatever you get from the controller should give you a range of 0..1 (the + 1.0 is to get you in the range 0..2)
