Bind issues

by Samuel Marcus · in Torque Game Builder · 11/12/2006 (2:15 am) · 5 replies

Because everyone enjoys bind issues...

When I use

moveMap.bind(keyboard,"q","function1();");
	moveMap.bind(keyboard,"w","function2();");

And then press q or w (or whatever you want to set) I get "Unknown Command" errors.

Now, I've established that this is because the object that function1 and 2 belong to was created as a ScriptObject-- if I use a function like getID() or some other built-in call, it will work fine. But I've defined function1 and 2 as functions for my object-- why can't the moveMap see them? The Game can; other objects can.... but moveMap can't see thre functions even if I give my ScriptObject a $Name and refer to it in the function call. Are ScriptObjects just bad news?

Er.. that's what I thought the issue was, anyway. I converted it to a t2dSceneObject and the same thing is happening. bindCMD(...) is acting similarly (but with more arguments).

Ok so it seems that you can only bind class-less functions to keys. Is that the case?

If you want to bind a function that is part of something other than the global namespace then you'll have to include the namespace in the bind.

When using "bind" you don't include braces or the semi-colon

moveMap.bind(keyboard, "q", function1 );

function1 in this case should accept a "%val" parameter that will be true on keypress and false on key release.

For "bindCmd" you specify a script command to run on keydown and another to run on key up. This could be a function call

moveMap.bindCmd(keyboard, "q", "function1OnPress();", "function1OnRelease();" );

or several separate commands.

moveMap.bindCmd(keyboard, "q", "function1OnPress();doMoreStuff();", "function1OnRelease();" );

You can also call methods on named objects or those you have a reference to such as

// named object
moveMap.bindCmd(keyboard, "s", "player1.moveDown(1);", "player1.moveDown(0)" );
// object using global var
moveMap.bindCmd(keyboard, "space", "$player.spawn(1);", "$player.moveDown(0)" );

where moveDown is a function in the player1 (or the class your player1 is) namespace and 1/0 is a parameter to indicate key press/key release to save having to have a separate moveDown and moveDownStop function.
