Hi!

I'm having a problem with a pick and drop function that was working
very well in VER 6.60 Pro

I now have VER 7.04 Pro with WindowsXP-home.
I have transferred all my ".wdl" scripts to Lite-C ".c".
Two of my levels work...So the migration is coming along fine.
Level 3 opens and works until I try to pick up the object.
Then I get the following message.

Error E1513: Crash in bougequest1j2
Program aborted

The code follows below:
Code:

---

 ENTITY* quest1j2;
ENTITY* tempj2;

/////////////
var enable_polycollision = 0;  //is set in main.c before function main()
////////////
int valeurclic = 0;

function bougequest1j2 () // August 1st 2007
{
	wait(1);
	valeurclic += 1; 
	if ( (valeurclic % 2) == 1) // The left side of mouse was selected
	{
		while (mouse_left == 1) {wait (1);}
		while (mouse_left == 0) 
		// move the object until the player presses the mouse button again
		{
			tempj2.x = mouse_cursor.x; 
			tempj2.y = mouse_cursor.y;
			tempj2.z = 500; // move the object 500 quants below the camera, 
			vec_for_screen(tempj2, camera); 
			quest1j2.x = tempj2.x;
			quest1j2.y = tempj2.y;
			quest1j2.z = tempj2.z;
			wait (1);
		}
	}
	else // drop the object
	{
		vec_set (tempj2.x, quest1j2.x); 
		quest1j2.z += 50; // drop the object 50 quants
		c_move(quest1j2,nullvector,nullvector,  
		IGNORE_MAPS | IGNORE_CONTENT | ACTIVATE_TRIGGER | USE_AABB  );
	}
}

The first nullvector, wont work because that is where your movement speed is supposed to go. So it should be:
c_move (quest1j2,vector ("x","y","z"),nullvector,....

Hi oldschoolj !

Did not work.

The level is stopped with the same message. And I can't use the //! to find out
wat is wrong.

Any suggestion will help.

The only thing I see that might go wrong in Lite-C is the vec_for_screen instruction, which expects a VECTOR* and not an ENTITY*. Try to add an ".x" to this (for both the entity pointer and the VIEW* pointer "camera").

And I do not quite see what the c_move is supposed to do - if both speeds are the nullvector, then the object will not move at all. Is this intended?

Hi Gnometech !

Thanks for the information. This morning, I looked at another of your messages
where you responded to Frederic about Vertors. So I went back and

Code:

---

 //The correct code follows below:
ENTITY* quest1j2;
 VECTOR* tempj2 = {x=0;y=0;z=0;}  


/////////////
var enable_polycollision = 0;  //is set in main.c before function main()
////////////
int valeurclic = 0;

function bougequest1j2 () // August 1st 2007
{
	wait(1);
	valeurclic += 1; 
	if ( (valeurclic % 2) == 1) // The left side of mouse was selected
	{
		while (mouse_left == 1) {wait (1);}
		while (mouse_left == 0) 
		// move the object until the player presses the mouse button again
		{
			 vec_set (tempj2, vector(mouse_cursor.x,mouse_cursor.y,500));   
			vec_for_screen(tempj2, camera); // voir manuel
			 vec_set (quest1j2.x,tempj2.x);   
			wait (1);
		}
	}
	else // drop the object
	{
		vec_set (tempj2.x, quest1j2.x); 
		quest1j2.z += 50; // drop the object 50 quants
		c_move(quest1j2,nullvector,nullvector,  
		IGNORE_MAPS | IGNORE_CONTENT | ACTIVATE_TRIGGER | USE_AABB  );
	}
}

So your comments about Vectors was the answer.
Now the code is shorter

As for the nullvector for the movement...the box (with this code) drops
where I want it. It falls below the camera view and does a collision.

Ps: look at my flags at a glance table in Lite-C contribution.
