How to use the 2D graphics processor:
|

Please see gpu.txt for information on this part.
|
||||
|
||||
How to use the digilines pistons:
|
||||
The following commands are accepted as strings: "extend" (extend the piston), "retract" (retract the piston), and "retract_sticky" (retract the piston, pulling one node like a sticky piston)
|
||||
You can also send a command as a table. If so, the fields that can be used in the table are as follows:
|
||||
* action: "extend" or "retract"
|
||||
* max: The maximum number of nodes to push/pull, cannot be set higher than 16. Set to 0 (or omit) when retracting to perform a non-sticky retraction.
|
||||
* allsticky: Pull a whole stack of nodes (like movestone), not just one.
|
||||
|
||||
How to use the digilines movestone:
|
||||
Commands for this node are in the form of a table, with the field "command" set to the desired action, and other fields providing parameters.
|
||||
The commands are as follows:
|
||||
* "getstate": Returns a table containing the following elements: "targetpos" (table representing the target position), "pos" (table representing the current position), and "moveaxis" (the current axis being moved along, nil if not moving)
|
||||
* "absmove": Moves to the absolute position specified by "x" "y" and "z". No axis can move more than 50m as a result of one command. If movements along more than one axis are needed, they are processed in alphabetical order (X,Y,Z).
|
||||
* "relmove": Same as absmove, but relative to the current position (for example, y=1 moves up 1m, not *to* Y=1)
|
||||
The available parameters for absmove and relmove are:
|
||||
* x: Target X position (for absmove) or target change in X position (for relmove)
|
||||
* y: Same, but for Y
|
||||
* z: Same, but for Z
|
||||
* sticky: Whether to pull nodes along behind the movestone
|
||||
* allsticky: Whether to pull a full stack of nodes like normal movestone (true) or just one like a sticky piston (false)
|
||||
* maxstack: The maximum number of nodes to push/pull, with the movestone itself counting as 1. Cannot be set higher than 50.
|
||||
* sound: "mesecons" to have the mesecons movestone sound play or "none" for no sound at all
|
||||
If any of x/y/z are omitted, then they default to the current position (for absmove) or 0 (for relmove).
|
||||
If any of maxstack/sticky/allsticky/sound are omitted, they default to the values last used.
