Making a NPC move.

[Swordwielder]

How would I make my Non Player Character walk back and forth between 2 points? And if my player character collides with him, how would I make the game end?

You would have to do something like the following.  The comments are self-explanatory.  Consult the manual for more detail, give it a try, and let us know how it works out. 

Code: ags

int NpcX[2];
int NpcY[2];
int NpcPos;

function RepExec() {
     // Wait for Npc to stop moving 
     if (!cNpc.Moving) {
          // Set the index for the next position
          if (NpcPos==0) NpcPos = 1;
          else NpcPos = 0;

          // Move NPC to the next position 
          cNpc.Move(NpcX[NpcPos], NpcY[NpcPos], eNoBlock);
     }
     // NPC is moving so check for collision
     else {
          if (cNpc.IsCollidingWithChar(player) {
              // Characters are colliding so do something 
          }
     }
}
