This is an extended version of KidBasic code-named KidBasic++.
The main motivation is to add statements and functions that are crucial for game development within the KidBasic language.
Its basis is a fork from the SVN revision 667. You'll find the current state of the vanilla project here.
Note that the compiled interpreter is still called BASIC256 for compatibility for existing scripts and start configurations.
-
ABORT- aborts BASIC256 immediately
-
ARGS- returns the arguments that were passed to BASIC256 from the command line with option -a
-
BREAKPOINT- forces the debugger to stop at this statement, user can choose debug/step afterwards
-
CLIPPINGRECT x , y , width , height- Sets the rectangle within the graph window into which graphical operations are able to paint to
-
CLIPPINGRESET- Resets the clipping to its default setting (clipping region is the complete graphsize)
-
FONTASCENT- returns the ascent of the the current font
-
FONTDESCENT- returns the descent of the the current font
-
IMGHEIGHT Image-FileName- returns the height of the image file (0 if not found)
-
IMGWIDTH Image-FileName- returns the width of the image file (0 if not found)
-
RECTIMG pseudo file name , x , y , width , height- Puts the region as a new image into the image buffer and assigns it to a pseudo file name.
- Subsequent imgload, imgwidth, imgheight can refer to this image by using that file name.
-
WAVPLAY [ channel , ] Wav-FileName [ , loop-number ]- loop-number has to be given if channel is given
- loop-number -1 means infinite loop
- loop-number 0 means only one playthrough
- defaults: channel = 0 , loop-number = 0
- Note that files are buffered, subsequent plays do not re-access the file system
-
WAVSTOP [(] [ channel ] [)]- defaults: channel = 0
-
WAVWAIT [(] [ channel ] [)]- defaults: channel = 0
