Thread: [PI] Npc forced movement mask

SERVER
NPC.java
Add the following fields

Code:

public boolean forcedMovementUpdateRequired;
public int forcedMoveStartX;
public int forcedMoveStartY;
public int forcedMoveEndX;
public int forcedMoveEndY;
public int forcedMoveCycleStart;
public int forcedMoveCycleEnd;
public int forcedMoveDirection;

Add the following methods

Code:

	public void appendForcedMovementUpdate(Stream str) {
		str.writeByte(forcedMoveStartX);
		str.writeByte(forcedMoveStartY);
		str.writeByte(forcedMoveEndX);
		str.writeByte(forcedMoveEndY);
		str.writeWord(forcedMoveCycleStart);
		str.writeWord(forcedMoveCycleEnd);
		str.writeByte(forcedMoveDirection);
	}

Code:

	public void forceMovement(int startX, int startY, int endX, int endY, int cycleStart, int cycleEnd, int direction) {
		this.forcedMoveStartX = startX;
		this.forcedMoveStartY = startY;
		this.forcedMoveEndX = endX;
		this.forcedMoveEndY = endY;
		this.forcedMoveCycleStart = cycleStart;
		this.forcedMoveCycleEnd = cycleEnd;
		this.forcedMoveDirection = direction;
		this.forcedMovementUpdateRequired = true;
		this.updateRequired = true;
	}

appendNPCUpdateBlock (still npc.java)
Add

Code:

if (forcedMovementUpdateRequired)
	updateMask |= 0x100;

right above

Code:

if (animUpdateRequired)
	updateMask |= 0x10;

Change

Code:

str.writeByte(updateMask);

to

Code:

str.writeWord(updateMask);

Add

Code:

if (forcedMovementUpdateRequired)
	appendForcedMovementUpdate(str);

right above

Code:

if (animUpdateRequired)
	appendAnimUpdate(str);

clearUpdateFlags(still npc.java)
Add

Code:

forcedMovementUpdateRequired = false;

somewhere

CLIENT
Method86 in client.java

Change

Code:

int l = stream.readUnsignedByte();

to

Code:

int l = stream.readUnsignedWord();

Right above

Code:

if((l & 0x10) != 0)

add

Code:

if((l & 0x100) != 0)
{
	npc.anInt1543 = stream.readUnsignedByte();
	npc.anInt1545 = stream.readUnsignedByte();
	npc.anInt1544 = stream.readUnsignedByte();
	npc.anInt1546 = stream.readUnsignedByte();
	npc.anInt1547 = stream.readUnsignedWord() + loopCycle;
	npc.anInt1548 = stream.readUnsignedWord() + loopCycle;
	npc.anInt1549 = stream.readUnsignedByte();
	npc.method446();
}

Command for testing it works

Code:

if (playerCommand.equals("testforcemove")) {
	for (NPC npc : NPCHandler.npcs) {
		if (npc != null) {
			int dx = npc.absX - (c.mapRegionX * 8);
			int dy = npc.absY - (c.mapRegionY * 8);
			npc.forceMovement(dx, dy, dx, dy + 5, 0, 30, 2);
		}
	}
}
