And the check:

PHP Code:

 if (!isBlocking(tiles[player.x+1.5,player.y+3])){
   player.y += 1;
  } 


So if the player is not touching the blocking tiles, the player will fall
(for platformer system)


Now I want to go advanced and make collision with certain NPCs..

So I was wondering if someone could help me write this.


The NPC

PHP Code:

function onCreated(){
 this.blocking = true;
 setShape(1, 32, 32);
 setImg("block.png");
} 


The on Created:

PHP Code:

function isBlocking(tile) {
  temp.blocktiles = {0,16,1024,1025,1026,1027,1028,1029};
  return (tile in temp.blocktiles);
  temp.blocknpc = //Check if the temp.npc.blocking == true
} 


The check:

PHP Code:

 if (!isBlocking(tiles[player.x+1.5,player.y+3])){
  if /*not colliding with npc that is blocking*/ {
   player.y += 1;
  }
 } 


something like this?

PHP Code:

function isBlocking(tile) {
  temp.blocktiles = {0,16,1024,1025,1026,1027,1028,1029};
  return
    tiles[player.x + 1.5, player.y + 2] in temp.blocktiles ||
    this.checkBlockNPCs()
  ;
}

function checkBlockNPCs() {

  temp.npcs = findareanpcs(player.x + 1.5, player.y + 2, 0.0625, 0.0625);

  for (temp.n : temp.npcs) 
    if (temp.n.blocking)
      return true;

  return false;
} 


but then im not sure its a good idea to be checking just a single pixel for collisions, graal movement usually checks the width of the players body (2 tiles or 32 pixels)
