Thread: Please help! Adding walkType for NPCs to the changeRegion packet?

I tried this:

Code:

		if (packetType == 210) {
			
		for (int i = 0; i < maxNPCs; i++) {
			if (npcs[i] != null) {
		if (npcs[i].walkingType >= 2) {
	        switch(npcs[i].walkingType) {

	        case 5: //west
	            npcs[i].turnNpc(npcs[i].absX -1, npcs[i].absY);
	            break;

	        case 4: //east
	            npcs[i].turnNpc(npcs[i].absX +1, npcs[i].absY);
	            break;

	        case 3: //south
	            npcs[i].turnNpc(npcs[i].absX, npcs[i].absY -1);
	            break;
	        case 2: //north
	            npcs[i].turnNpc(npcs[i].absX, npcs[i].absY +1);
	            break;

	        default: // applies to all npc who are only standing, remove if not needed
	            if (npcs[i].walkingType >= 0) {
	                npcs[i].turnNpc(npcs[i].absX, npcs[i].absY); //makes it when npcs move they dont turn back to one direction
	            }
	            break;
	        }
	    		}
			}	
							
		
		if(npcs[i].walkingType == 1) {
			if(Misc.random(3)== 1 && !npcs[i].walkingHome) {
				int MoveX = 0;
				int MoveY = 0;			
				int Rnd = Misc.random(9);
				if (Rnd == 1) {
					MoveX = 1;
					MoveY = 1;
				} else if (Rnd == 2) {
					MoveX = -1;
				} else if (Rnd == 3) {
					MoveY = -1;
				} else if (Rnd == 4) {
					MoveX = 1;
				} else if (Rnd == 5) {
					MoveY = 1;
				} else if (Rnd == 6) {
					MoveX = -1;
					MoveY = -1;
				} else if (Rnd == 7) {
					MoveX = -1;
					MoveY = 1;
				} else if (Rnd == 8) {
					MoveX = 1;
					MoveY = -1;
				}
				
				if (MoveX == 1) {
					if (npcs[i].absX + MoveX < npcs[i].makeX + 1) {
						npcs[i].moveX = MoveX;
					} else {
						npcs[i].moveX = 0;
					}
								}
				
				if (MoveX == -1) {
					if (npcs[i].absX - MoveX > npcs[i].makeX - 1)  {
						npcs[i].moveX = MoveX;
					} else {
						npcs[i].moveX = 0;
					}
								}
				
				if(MoveY == 1) {
					if(npcs[i].absY + MoveY < npcs[i].makeY + 1) {
						npcs[i].moveY = MoveY;
					} else {
						npcs[i].moveY = 0;
					}
								}
				
				if(MoveY == -1) {
					if(npcs[i].absY - MoveY > npcs[i].makeY - 1)  {
						npcs[i].moveY = MoveY;
					} else {
						npcs[i].moveY = 0;
					}
									}
								}
							}
						}
					}

[/spoiler]

which went horribly wrong, and didn't help at all! How would I link these if statements so that when packet 210 (the one to change regions) is initiated, it calls them and checks the npc direction?

Thanks!

Baylo

in npc.java look for these methods

Code:

public static int FocusPointX = -1;
	public int FocusPointY = -1;
	public int face = 0;

	private void appendSetFocusDestination(Stream str) {
		if(FocusPointX != -1){
			str.writeWordBigEndian(FocusPointX);
			str.writeWordBigEndian(FocusPointY);
		} else {
			int x = absX;
			int y = absY;
			if(walkingType != 1){
				//0= north 3= west 2=east 5=east 4=south
				switch(walkingType){
				case 0: //north
					y++; break;
				case 2: //east
					x++; break;
				case 3: //west
					x--; break;
				case 4: //south
					y--; break;
				}
			}
			str.writeWordBigEndian(x * 2 + 1);
			str.writeWordBigEndian(y * 2 + 1);			
		}
		
	}

	public void turnNpc(int i, int j) {
		FocusPointX = 2 * i + 1;
		FocusPointY = 2 * j + 1;
		updateRequired = true;

	}

and stuff if you have them replace them if you dont have them add them

Thanks for the reply -

I've added that, and it didn't actually do anything for me :O

What I'm trying to do is actually add in the code I have, but in somewhere other than process() so that it's not called every 600ms or w/e - I've read that it's best if I use the region loading packet to do this, but I'm not sure how

Thank you anyway though

Bump! If anyone knows how to call this information for the changing regions packet, please let me know!

Bump!

Bump!
