How to Update function param value ?

Hi,

   I need to make a common function which would set X,Y properties of any object passed to it.

ex: function hideObject :(Action) Set Function.Param(0).X to -100

                         (Action) Set Function.Param(0).Y to -100

I am not able to find any way in which I can access & set function param values in actions, I can only see System 0> Set Value of variables not Object.variable ?

Your help would be highly appreciated...

-Thanks

do you mean "call function xxxxx" with a specific param

in the dialog box of "call function" there is a "add parameter" or something like that below

You'd put the objects in a family and pass the object's UID to the function. Then in the function have:

Family: Pick by UID Function.Param(0)
   -> Family: Set X to -100
   -> Family: Set Y to -100

ramones would it be possible to provide a sample capx, I am actually confused in making this work in C2 cause I did not find any arbitrary variable setter action.

-Thanks

I was just wrestling with this myself and figured out how it works:

Whenever you call the function, add the new parameter into the parenthesis. Here would be an example in the Event sheet:

SYSTEM --> On start of layout --> Function --> Call "nameOfYourFunction?(7)

Then to change it on the next use would be:

SYSTEM --> On start of layout --> Function --> Call "nameOfYourFunction?(559)

Example: hideObjectFunction.capx

Thanks ramones —

ramones Thanks for the example, but if you look at it this function hideObject gets tied for a specific Sprite object. What I want to do is call hideObject for any Sprite. Also want to void checking in the function which sprite this function has been called on.

Something like:

SpriteA -> Call hideFunction(IID)

SpriteB -> Call hideFunction(IID)

SpriteC -> Call hideFunction(IID)

In hideFunction

Function.Param(0).X = -100;

Function.Param(0).Y = -100;

I'm not sure what you mean. In the example it will work for any object in the Sprites family. It works like this as well:

ramones sorry I overlooked that you had used Families to combine all Sprites in the project.

-Thanks
