Simple Movement

Here is a good way to move your object in all directions very easily.

PHP Code:


		
			
//#CLIENTSIDE  // Makes events all processed on the client comp



function onCreated()  //Action is called when script is read

{



  disAbleDefMovement();  //Disables Default movement for player

}



function onKeyPressed( code, char)  //Called when ever the client pushes a key on the keyboard

{



  k = code;  //make k equal the code number of what ever key is pushed



  player.x += (( k == 39) - ( k == 37))/16;  //  if k equals number, it is 1, if not it is 0



  //so if the player pushes left arrow it be player.x += 0 - 1;  



  player.y += (( k == 40) - ( k == 38))/16;  //same as above just on the y-axis



}

Hmm, there's a problem with this.
One, there's no loop, you're calling it on keypressed(unless you want it to be a more systematic movement than fluid). As I believe, keypressed is called when the key is first pressed, then the repeat(which is defined personally in the keyboard properties, so this will react very slowly if the person has the key repeat very low). Also, I think it'd be better if you used keydown(0-3), they're the default keys for arrow movement, and are also compatible with gamepads.

Update

PHP Code:


		
			
//#CLIENTSIDE 



function onCreated()

{



  disAbleDefMovement();

  onTimeout();

}



function onTimeout()

{



  player.x += (( keydown(3)) - ( keydown(1)))/16;  



  player.y += (( keydown(2)) - ( keydown(0)))/16;  



  setTimer( 0.05);

}

Do you want to add some onwall checks later? :]

Disable is one word -.-

disableDefMovement();

instead of disAbleDefMovement();

You could do that without a capital A ;P
Anyways, I think you should add the checks, just for the sake of it. May help out some peeps.

It doesnt really matter how the A is...

update

PHP Code:


		
			
//#CLIENTSIDE 

function onCreated()
{

  disAbleDefMovement();
  onTimeout();
}

function onTimeout()
{
  
  nx = player.x;
  ny = player.y;

  nx += (( keydown(3)) - ( keydown(1)))/16;  
  ny += (( keydown(2)) - ( keydown(0)))/16;  

  if ( !( onwall( nx + 1.5, ny + 2)))  {

    player.x = nx;
    player.y = ny;
  } 

  setTimer( 0.05);
}

I would atleast define the middle of the player ;P

PHP Code:


		
			
if ( !( onwall( nx + 1.5, ny + 2)))  {



  player.x = nx;

  player.y = ny;

}
