Arcade/!Gush/Data/Prototypes
This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

# Example prototypes file, for !Gush demo # # This is a 'retrospective' spec document; you won't understand it until # you've looked at an example of what it describes :-) # # A list of variables, of the syntax <variable> = <value>; there must be # at least one space either side of the = sign. # # -- Spaces are significant in the <value> part # -- Blank lines and those starting with a hash (#) are ignored # -- Each prototype definition must start with the 'id' and 'frames' variables, # then you can have any or none of the others, then a number of 'frame' # variables before the next 'id' variable. # # Valid variables are: # # id = <four-character ID> <no. of frames> # starts each prototype definition off # handler = <handler> specifies the function name of the object's handler # which is expected to be linked with the object file. # objflags = <list of flag names> # These correspond to the object_flags in the h.Popcorn header # file. # frame = <frame name> [S@x,y] [C@x,y] # There should be as many 'frame' variables as specified in the # 'frames' variable above. S and C correspond to size and # centering informaton for each frame; if they are omitted, they # are worked out from the sprite files, assuming they are # Popcorn sprites. # Ball objects # # These have only one frame, but have a variety of flags set. They # need 'velocities' and 'gravity' to ensure smooth movement, though # try removing 'gravity' from one or both ball definitions for some # not-quite-right effects. id = GENR 0 handler = generator_handler objflags = attn_every id = BLUE 1 handler = ball_handler objflags = std_plot velocities collide gravity attn_plotout frame = <Gush$Dir>.Graphics.Blue id = YELO 1 handler = ball_handler objflags = std_plot velocities collide gravity attn_plotout frame = <Gush$Dir>.Graphics.Yellow
