virtualx-engine/modules/gdscript/gdscript_editor.cpp
anakimluke 370f84f41c Removed whitespaces around arguments of functions. 
Functions automatically generated by conneting
signals via GUI put whitespaces around the
arguments of the generated function. This is
inconsistent with the style guide.

This commit fixes that.
