LUA-script-problem (question)

  • #1, by cpt_capslockMonday, 09. September 2013, 05:36 11 years ago
    boenas scriptas all together !

    i wanted to have my mousecursor change its state to use clicking the right mousebtn. and i got that so far.
    the problem is : i wanted it to do that in a "normal" scene ..but there are others like : mini-games and so on, in witch that should NOT be possible.
    So the solution i think is to set in the game main options menu the right mouse button to call an action that checks :

    if (for example the condition wich i set in a certain scene as true) is true,
    THEN call script (a)

    and in this script (script a from above) i got :

    if current command is "Standart-Befehl"
    set command "rightclick-use"
    set cursor "ACTION-MAUS"
    set cursor "default-MAUS"
    set command "Standart-Befehl"

    end if
    but this script isn't doing anything is my first attempt to write a script .
    and an answer is appreciated the workflow can continue.

    KlaatuVerataa NEKTu !

    because it's not a Lua Script, it's editor action parts wink

    via Lua, there are a lot more possibilities that you can do to query if something should happen or not because we can use the "and" and/or the "or" operators to string together multiple conditions into a single query.

    you can actually do what you are wanting via the editor alone...

    you could query if scene is x...
    or simpler solution is to use a value instead of a condition because you can use infinite numbers in a value as opposed to true/false in a condition...

    if value "value_name" is 1
     do some action
     if value "value_name" is 2
     do something else
     do something if none of above are correct

    in the editor there needs to be same amount of "end" as "if"

    hope this helps you a little bit?

    i am confused, because logically (syntax-wise) i understand what i have to do.
    the problem is ... i would need the exact script, because :
    setcursor doesnt seem to work and i cannot find a list of commands for the engine script


    i know ..its annoying .. but please ?

    can you give me a rundown on exactly what it is you are wanting to do please?

    P.S: the Lua Script syntax can be found on the old 2d wiki or via the new one...

    the data structure page contains all the readable/writable content & the scripting page gives you a few examples & information on scripting in VS. the player commands page are exclusive Lua commands for VS & the basic Lua page is just something I'm working on to introduce general Lua script basics & beyond.

    P.S: what you did in script above was actually action parts & should have been done inside of the editor itself; see attachment below for a quick example.

    P.P.S: you don't technically have to do the set cursor command if you are using multiple command buttons as you can assign a default cursor to each command/button - which means you only need to do the set cursor action part if you are wanting to set a different cursor other than the currently assigned default cursor for x command.

    Hey guys. taking up this topic.

    What if i want to set my cursor with the lua script? What is the code?

    I use your global command checker and then ask if a certain condition is true. if it is true, then set cursor and set command.

    Not possible to set it with Lua script as there is currently no GameCurrentCursor data structure field. You need to create some called by other action parts which contain set cursor action parts. You can call the actions you created via Lua script by using the startAction() function.


    P.S: the command checker script was not created for the purpose you are intending. It was created for a coin interface system in which it automatically determines which command buttons on the interface should be active by searching for specific actions listed in the action list of the saved / current interaction object.
