[tzoli]

Hi

Please help!I use draw_from to make in split screen.

I assume you're using speckford's splitscreen demo, in that case:

bullet -> create actor -> script editor

Code: Select all

bulletcount ++;

Makes it so we know how many bullets there are

bullet -> destroy actor -> script editor

Code: Select all

bulletcount --;

Still just lets us know how many bullets

viewP1 -> draw actor -> script editor

Code: Select all

int i;//needed for loop
erase(0, 0, 0, 1);

for(i=0; i < bulletcount; i++)//loop through all the bullets
{
Actor * this = getclone2("bullet", i);//so we can use pointers for x & y, can't do bullet.i.x
draw_from("bullet.i", 320+this->x-p1.x, 160+this->y-p1.y, 1);//draw that bullet
}


viewP2 -> draw actor -> script editor

Code: Select all

int i;
erase(0, 0, 0, 1);

for(i=0; i < bulletcount; i++)
{
Actor * this = getclone2("bullet", i);
draw_from("bullet.i", 320+this->x-p2.x, 160+this->y-p2.y, 1);
}


almost same thing as last code, but for viewP2

Global Code

Code: Select all

Actor * getclone2 ( char * actorName, long cloneNumber )
{

  char resultString[256] = "";
  char cloneNumberAsString[10];
  Actor * resultActor;

  strcpy ( resultString, actorName );
  strncat ( resultString, ".", 1 );
  sprintf (cloneNumberAsString, "%i", cloneNumber);
  strncat  ( resultString, cloneNumberAsString, 10 );

  resultActor = getclone(resultString);

  return resultActor;
}

Jazz_e_bob's awesome code so we can get the clone of the bullet in order to draw him

Thanks

Could someone go into detail about what this Global Code does? I sure would appreciate it
It sort of makes sense to me, But when I try to use it, it says "Error line 2: Illegal redefinition of builtin function getclone2".

Thanks in advance!

The Global Code part in that code is just a function to get access to single clones by their actor name and cloneindex. The reason why you get that error is that the 1.4.1 version of GE already has a built in getclone2-function, so you can't define a new function with the same name.

And just so you know, that version of the getclone2 function in unnecessarily complex. It is using a bunch of str functions, first to set the resulting string, then concats a period, then uses sprintf to set another string with the cloneindex value, and then cat that onto the resultString. You could do all of that with one sprintf call. Here is the shorter version.

Code: Select all

Actor*
getclone2(char* actor_name, int c_index)
{
    char buffer[30];
    sprintf(buffer, "%s.%d", actor_name, c_index);
    return (getclone(buffer));
}

Oh gosh, I forgot I made a splitscreen demo a while back
the memories, haha
