Big Fatal exception Error during runtime

[Gold Dragon]

I told you guys would hear more of me but I hoped it wouldn't have been this soon.     :'( :'(

ok I created a new cursor mode called 'move' in the Cursor's editor

then in the global Script I created this function to simulate moving an Object from one plance to another.
----------------------------------------------
function Move_Object(){
 int Objint;    // integer to store the object number

  // On the first Left click get the object # and store in Objint
  on_mouse_click (LEFT);{
   Objint=GetObjectAt(mouse.x,mouse.y);
 }

 // On the Second left click move the object to the new position the mouse is at
 on_mouse_click(LEFT);{
   MoveObjectDirect(Objint,mouse.x,mouse.y,3);
 }
}
----------------------------------------------

in the room script it looks like this
----------------------------------------------
// room script file

import function Move_Object();  // Import Move_object() from global Script

function room_a() {
 // script for room: Player enters screen (before fadein)
SetObjectIgnoreWalkbehinds(4,1);
SetObjectIgnoreWalkbehinds(5,1);  
}


// this is the script that is excuted when the 'move' cursor is activated in the interactions menu for Object 5

function object5_a() {  
 // script for object5: Move object
Move_Object();
}

-----------------------------------------------

When I click on the object I want to move when testing the game. I get this "illegal exception" message

An exception 0xC00000FD occured in ACWIN.EXE at EIP=0x0044B8E ;program pointer is+6, ACI version 2.56.627,
gtags (0,64)

(the message to notivefy CJ)

(Room 1 script line 116)

-------------------------------------------------

the script line 116 is the line
MoveObjectDirect(Objint,mouse.x,mouse.y,3);

I'm really sorry about this mess..

if you have another way to move an object during runtime by the user from one position to another please let me know.

Well, it really shouldn't be crashing like that, I"ll have to look into why it's not giving a better error message.

Basically, I think you're misunderstanding how the AGS events system works. Your Move_Object function is calling on_mouse_click, expecting to wait for the next mouse click.

However, on_mouse_click is just a normal function, and it gets run by AGS automatically when the user clicks the mouse. Calling it in the manner you have done will not wait for a mouse click, it will just run the script code.

You need to approach the situation differently, using an event-based approach rather than procedural.

Each time the user clicks the mouse, the on_mouse_click function will get run. So, you need to add some code to that to do your processing.

For example, your Move_Object function could set a global variable to indicate that a move has been initiated.

Then, the on_mouse_click function could check if that variable was set, and if so then it could store the object number, and so forth. Something like:

function Move_Object(){
SetGlobalInt(1,1);   // set globalint 1 to 1
}


then inside on_mouse_click:

if (GetGlobalInt(1) == 1) {
 int Objint = GetObjectAt(mouse.x,mouse.y);
 SetGlobalInt(2, Objint);  // store the object number
 SetGlobalInt(1, 2);
}
else if (GetGlobalInt(1) == 2) {
 MoveObjectDirect(GetGlobalInt(2),mouse.x,mouse.y,3);
}

Thank you I'll try that
