Errors

Unable to open OpenSpades on macOS

Due to recent changes in the security system of Mac OS X, you might see the message that says "it can't opened because it is from an unidentified developer" when you try to launch OpenSpades by double clicking the application icon. This can be circumvented by right-clicking the icon, and then clicking "Open".

Another option will pop up. Click "Open" to launch OpenSpades.

Bad allocation

Bad allocation errors occur when OpenSpades is unable to reserve enough memory for itself.

This usually happens if you have too many programs open or your system has insufficient memory to load OpenSpades.

Moving font-unifont.pak out of the Resource folder (or simply deleting it) might solve this problem, but some special characters will be no longer visible after doing that.

Incorrect behavior

Some keys don't work in-game (Linux)

If some of your keys don't work in-game, please close OpenSpades and relaunch it with the English (US) keyboard layout.

Graphics

Screen is off center

This problem might be caused by HiDPI scaling of a modern version of Windows. Right click OpenSpades.exe, go to Properties, and click the Compatibility tab, in which you can find the checkbox to disable the HiDPI scaling.

Installation

libpng12.so.0: undefined symbol: _png_set_longjmp_fn

Compile SD2L_image with --disable-png-shared. Like this:

./configure --disable-png-shared && make && sudo make install

-- #252

Performance

Drastic reduction in frame-rate while firing SMG

• /r_cameraBlur 0 or disable Post-Effects → Custom → Camera Blur.
• Disable "Hit Detection Debugger", which takes screenshot every time you fire a weapon.
