• make compile
  • compile the source code
• make run script=./your_script.mscript
  • execute with the specified script
• make info
  • generate documentation
• make clean
  • delete root directory images and and compiled code

MoodScript

The OkuyasuEngine interprets commands in MoodScript

command1  
command2  
parameter1 parameter2  
command3  
paramater1 paramater2

Some commands are followed by parameters while some are not.
Here is the commandset (parameters enclosed in parentheses must be one of the enclosed options) Anything that is not in the command set is a comment
"-" denotes a command with no parameters

command	parameters	purpose
pen-color	red green blue	sets the color of the edges of the image
bg-color	red green blue	sets the color of the background of the image
move	dx dy dz	appends a transformation operation to the coordinate stack
scale	sx sy sz	appends a scaling operation to the coordinate stack
rotate	(x, y, z) theta	appends a rotation operation to the coordinate stack
push	-	push the current coordinate system to the stack
pop	-	pop the current coordinate system to the stack
line	x0 y0 z0 x1 y1 z1	draws a line
circle	cx cy radius	draws a circle
hermite	x0 y0 x1 y1 rx0 ry0 rx1 ry1	draws an hermite curve
bezier	x0 y0 x1 y1 x2 y2 x3 y3	draws a bezier curve
sphere	x y z radius	draws a sphere
torus	x y z inner_radius outer_radius	draws a torus
box	x y z width height depth	draws a box
clear	-	removes all shapes from the image
pause	-	pauses the script execution
save	filename.ppm	write the current image to a filename.ppm
save-convert	filename.ppm width height	writes the current image to filename.ppm and converts it to fileimage.png
display	-	display the current image in an JFrame
display-custom	xresolution yresolution	display the current image in an JFrame of the given resolution
