Menu exit method
At this time, you just need to click something with the mouse, such as weapons, and then press the space bar to return normally. The value of 0.54 shows that there is an unsolvable problem.
There are two solutions:
1: game support handle. If you use the handle, you won't encounter the problem of being unable to quit.
2. Full keyboard operation (no mouse). Modify the keyboard operation settings as follows.
Press i to open the menu. Click Configure to enter the key settings.
After entering the setup screen, because you are using full keyboard operation, you only need to change the keyboard line and set it according to your own preferences. In the process of key setting, if your setting conflicts with the preset key, the preset key will be eliminated by default. Remember to make up the new settings.
Remember to click done in the upper left corner after setting, so that you can easily exit the menu and operate with full keyboard.
In the menu, make sure that the default key is set to E(submib). The default key to cancel the exit is the space bar (jump). Please operate according to the settings you modified.
