Thread: Get the mouse x , y?

So i have been working on a game and i want to shoot something but my missile insted of going to targetX and tarrgetY it goes little bit off, it can go only some direction what is the problem?

I want it to go in all of the directions but it doesn't! Please help!

Welcome to the forum! Please read this topic to learn how to post code in code or highlight tags and other useful info for new members.

it can go only some direction what is the problem?

How would we, could we know?

Post your code in code tags per the above link that aims/shoots the missiles. Even better, post a short, runnable example that demonstrates the problem.

If you haven't already, add a class that implements MouseListener and MouseMotionListener to your main frame - whichever you're using of the awt version of Applet/Frames or the Swing JApplet/JFrame - using addMouseListener(this) and addMouseMotionListener(this). In your MouseListener implementation, add code in the overridden mouseMoved function to assign the MouseEvent's getX() and getY() return values to variables, then call them from your main class every repaint() and assign them to your targeting variables.

Basically, read up on MouseListener and MouseMotionListener.

Well i have posted the github! if you saw the image i posted you wouldn't tell me this, because i have already done that and i have the problem with my missiles going to the mouse x,y! And i don't use JPanel i use buffer strategy and i don't need to use repaint() because its done every time it can! I don't think that you have read the post but you only read the title of my post!

Note the very first line of my response - 'If you haven't already, ...'. I'm not going to dig through your entire project to debug your code for you. You gave a cursory explanation of your problem, so I gave a cursory response. If you want help, figure out where the problem is and provide more information than "I want it to go in all of the directions but it doesn't! Please help!".

this is a code segment from one of my tower defense games.

public static double[] bulletVel(SoldierParent soldier, ZombieParent zombie)
	{
		double velX = zombie.getX() - soldier.getX();
		double velY = zombie.getY() - soldier.getY();
		double distance = Math.pow((Math.pow(velX, 2)+Math.pow(velY, 2)), .5);
		double speed = 24;
		@SuppressWarnings("unused")
		double checkSpeed = Math.pow((Math.pow(velX/distance*5, 2)+Math.pow(velY/distance*5, 2)), .5);
		//System.out.printf("VelX = %f\tVelY = %f\tspeed = %f\n",velX, velY, checkSpeed);
		double vel[] = {(velX/distance)*speed,(velY/distance)*speed};
		return vel;
	}

I'm sure you can adapt the code to what you need.
you can throw this in for the x and y coords.

Point point = MouseInfo.getPointerInfo().getLocation();
	int x = (int) point.getX();
	int y = (int) point.getY();

If you read the post you wouldn't sad 'If you haven't already....' Because i have said "my missile insted of going to targetX and tarrgetY it goes little bit off" when i said targetX and targetY i meant the mouse position!

There was no way for me to know that within the confines of your post. I'll refer back to what GregBrannon posted initially:

Provide some demonstrable code within your posts that indicates the issue you're having. If you aren't willing to do that, why should we be willing to sort through your code to figure out what you're trying to do and how to make it work?

"targetX and tarrgetY" does not imply mouseX and mouseY. Even had you said mouseX and mouseY, there's no guarantee your implementation uses a MouseListener or a MouseMotionListener. Understand that you're asking people for help, and either provide a context for us to do so, or solve your problem on your own. Getting annoyed at the answers people who are helping you for free are giving is counter-productive.

That said, I'll ask once more - where in your code is the issue occurring? Post the code that controls the trajectories of your projectiles in a response post, and it would be far easier to diagnose the issue you're having and solve it.
