Invoking a function in multiple scripts...
Hi. If I have several instances of an object/script, how can I invoke a function in all of them (for example, each instance of Script A has variable B in it, each variable B has a different value, but I want to subtract 1 from every variable B)? I know that static functions cannot reference instance data (like variables that would have different values ...right?). Is there a way to work around this?
I'm confused. Do you think you could elaborate a bit?
Can you clarify ... do you have a Script A attached to multiple objects and what you are asking is for a function in the script to be executed once for each instance of the Script found in each of the objects that has it attached?
You could have all your objects with Script A be children of a single global game object and then send that global game object a BroadcastMessage indicating a Method in Script A that subtracts 1 from variable B.

Of, you could just use GameObject.FindGameObjectWithTag() and have tagged all the objects with Scipt As. Then, loop through the results and SendMessage() to them to call the Method subtracting 1 from variable B.

Thanks for the reply. $$anonymous$$y code has gotten more complex that just subtracting a value from a variable. I put everything in Script A that I want to invoke in function "Level". When I try to send the message, I get this error "GameObject.FindGameObjectsWithTag("Tiles").Send$$anonymous$$essage("Level");" What am I missing?
What you want to use is : gameObject.sendMessage()
Think it may do what what you need:
