Params Problem

PHP Code:


		
			
NPC1:



function onCreated()

  {

  foo( "bar" ); // returns false;

  }



public function foo()

  {

  NPC2.bar( "foo" );

  return params;

  }

PHP Code:


		
			
NPC2:

function onCreated()

  {

  NPC1.foo( "bar" ); // returns "foo,";

  }



public function bar()

  {

  return params;

  }

Inconsistency 1:
When called from within the function, params variable is NOT set. When called outside, it IS set.

Inconsitency 2:
When calling an external function, params variable are overwritten. ( Should be kept the same within the process )

Temp Fix 1: Use function foo( param1, param2 ), but limits the amount of params you COULD potentially have!

Temp Fix 2: temp.oparam = params; foo(); params = temp.oparam;

The params[] array is only set when a script function is called from outside, or when an event is invoked on a gani script (and you are using if (playerenters) etc. instead of onPlayerEnters). There is also only one params[] for the whole script engine, so it gets overwritten. It would be too slow to copy the function parameters to a separate array on each function call, also there are many scripts relying on the fact that you can access the original params[] array in subfunctions.
