this is a 3d starter you can build anything of of it. to add more squares/triangles/any shape you want press 0 then go to the position you want the first corner to be and press space then add the x, y and z when it asks you the x y and z And the type (please add G for the type as to not destroy the entire project) to get out of editor mode press 0 again. if you want the platform to be a jumpy platform or red platform then create green platform press c then fill out the xyzs then when it asks for tipe type JUMP for jumpy platforms and R for danger. sometimes the cube will not be solid if that happens then delete it and redraw it. a good way to test if it is solid is to see if your shadow touches is. (red cubes do not affect the shadow)
more coming soon such as switching levels and level saving and other entitys, and maybe mobile mode. for movement arrow keys for looking up, down and left right. wasd for strafing and moving back and forwards space to jump. when you enter editor mode the space button is used for something else so use the up and down arrow keys to look up and down. while in editor mode u to undo the last cube you just drew, c to redo the xyzs and type of the last cube you drew.
