Im trying to get the Player to move Forward exactly one block from its last position. So lets say his last position was 11.54321 etc... I would like him to stop at 12.54321 if he was moving in the Positive X direction. I know I have to account for the player movement speed, and so I made a conditional, but at no point in time are the players previous X coordinate equal to its new X coordinates. Please Help!

 

Here is the Conditional:

 

		new Timer().schedule( 
	        new java.util.TimerTask() {
	            @Override
	            public void run() {
	        		double x = Minecraft.getMinecraft().thePlayer.posX;
	        		System.out.println(x);
	        		System.out.println(x+.5);
	        		boolean atPosition = true;
	        		Minecraft.getMinecraft().thePlayer.rotationYaw = Minecraft.getMinecraft().thePlayer.rotationYaw+rotation;
	        		Minecraft.getMinecraft().gameSettings.keyBindForward.setKeyBindState(Keyboard.KEY_W, true);
	        		while(atPosition){
	        			System.out.println(Minecraft.getMinecraft().thePlayer.posX);
	        			if(Minecraft.getMinecraft().thePlayer.getPosition().getX() == x+1){
	        				Minecraft.getMinecraft().gameSettings.keyBindForward.setKeyBindState(Keyboard.KEY_W, false);
	        				Minecraft.getMinecraft().thePlayer.rotationYaw = Minecraft.getMinecraft().thePlayer.rotationYaw+rotation;
	        				atPosition = false;
	        			}
	        		}
	        		atPosition = true;
	        	}
	        },
	        0
	);

Ignore the Print statement, I was just debugging

Because the position is a float, using == will almost never be true. It especially doesn't help that timing will be less than perfect, so you need to have a tolerance allowance.

 

It would be better to check for having passed the desired location and aborting as soon as it is detected.

 

If you've ever tried to position yourself exactly in the center of a block yourself, you would know how tricky it is to be exact with key input.

Ah ok, So it will never be precise, but if I was to change the previous position to a float, would it be more accurate?

Ok so I changed them to a float to allow for a shorter range of numbers, and also added tollerance. But it will not stop, it will still go on forever.

 

		new Timer().schedule( 
	        new java.util.TimerTask() {
	            @Override
	            public void run() {
	        		float x = (float) Minecraft.getMinecraft().thePlayer.posX;
	        		System.out.println(x);
	        		boolean atPosition = true;
	        		Minecraft.getMinecraft().thePlayer.rotationYaw = Minecraft.getMinecraft().thePlayer.rotationYaw+rotation;
	        		Minecraft.getMinecraft().gameSettings.keyBindForward.setKeyBindState(Keyboard.KEY_W, true);
	        		while(atPosition){
	        			if(((float)Minecraft.getMinecraft().thePlayer.posX) >= x+1){
	        				Minecraft.getMinecraft().gameSettings.keyBindForward.setKeyBindState(Keyboard.KEY_W, false);
	        				Minecraft.getMinecraft().thePlayer.rotationYaw = Minecraft.getMinecraft().thePlayer.rotationYaw+rotation;
	        				atPosition = false;
	        			}
	        		}
	        		atPosition = true;
	        	}
	        },
	        0
	);

Well, if the player is moving in the negative-X direction.....

I fixed it, Thank you for your assistance
