Part7 sample DSA code "MTA"

Summary

Parsing "MTA"

"M" is the operator.
"T" and "A" are parameters.

You always check the reference to write DSA program, also trial and error.

"MTA" meaning

"M" means "standard Message".
"T" means message type "Toggle".
"A" means message target is pointed by "Parameter A".

"MTA" is converted into "MT". because "A" is default parameter, it is just omitted.

Currently 2 or 3 sources available

Reference by kentaro-k.21 (available at this site):

Note: most part of my reference is rewrite from Paul's reference.

From my reference, look at Operations syntax section in DSA reference.

"2. standard Message" is that.

[<next state>] "M" [<delay>]
      <message type> [<target>]

This representation is formatted by quasi BNF syntax. (See also: http://en.wikipedia.org/wiki/Backus-Naur_form)

<next state> is omittable because enclosed by "[" and "]". So, it is omitted. By omitting, running is continued at current state.

<delay> is also omittable. By omitting, no delay occurs.

<message type> is message type. Select one of "N" / "S" / "C" / "T". You cannot omit it.

<message type> :: = "N" |
      "S" | "C" | "T"

default is S N means do nothing S Set C Clear T Toggle

<target> specify message's destination. You can omit it.

In our case, "Parameter A" points the door. We placed a DSA actuator with such a parameter. So, use "A".

But "A" is default selection according to grammer description. So CSBuild may omit "A", you'll see only "MT" in next editing time.

<target> :: = "A" | "B" |
      "*" | <absolute location>

default is A A means use first actuator parameter B means use second actuator parameter * means use <location> from stack pos:2; level:6; x:5; y:5

Rain` has posted some DSA samples can be run immediately with CSBwin.
But their useful samples seem to be off-line for now.

Launch CSBuild.
