JAVA: mouseDragged getX and getY raw data erratic

I am trying to code a paint like program (for fun), but to challenge myself I tried to do it using setRGB method, but I see that when I move the mouse fast the behavior of the stroke gets erratic, do you know how to "soft" the data get from methods getX and getY? or why I am getting random points colored
Thank you in advance and sorry for my english. :)

What is a NullPointerException, and how do I fix it?

Closed 4 years ago.
My code is:
public void move() {
moveX();
moveY();
}
public void moveX() {
if(xMove > 0) {
int tx = (int) (x + xMove + bounds.x + bounds.width) / Tile.TILEWIDTH;
if(!collisionWithTile(tx, (int) (y + bounds.y) / Tile.TILEHEIGHT) && !collisionWithTile(tx, (int) (y + bounds.y + bounds.height) / Tile.TILEHEIGHT)) {
x += xMove;
}
} else if(xMove < 0) {
int tx = (int) (x + xMove + bounds.x) / Tile.TILEWIDTH;
if(!collisionWithTile(tx, (int) (y + bounds.y) / Tile.TILEHEIGHT) && !collisionWithTile(tx, (int) (y + bounds.y + bounds.height) / Tile.TILEHEIGHT)) {
x += xMove;
}
}
}
public void moveY() {
if(yMove < 0) {
int ty = (int) (y + yMove + bounds.y + bounds.height) / Tile.TILEHEIGHT;
if(!collisionWithTile((int) (x + bounds.x) / Tile.TILEHEIGHT, ty) && !collisionWithTile((int) (x + bounds.x + bounds.width) / Tile.TILEWIDTH, ty)) {
y += yMove;
}
}
if(yMove > 0) {
int ty = (int) (y + yMove + bounds.y) / Tile.TILEHEIGHT;
if(!collisionWithTile((int) (x + bounds.x) / Tile.TILEHEIGHT, ty) && !collisionWithTile((int) (x + bounds.x + bounds.width) / Tile.TILEWIDTH, ty)) {
y += yMove;
}
}
}
protected boolean collisionWithTile(int x, int y) {
return room.getTile(x, y).isSolid();
}
but when I run it I get a NullPointerException with this StackTrace:
Exception in thread "Thread-0" java.lang.NullPointerException
at com.pixelandbitgames.entities.creature.Creature.collisionWithTile(Creature.java:69)

at java.lang.Thread.run(Thread.java:748)
I do not see where this is coming from as collisionWithTile has all its parameters filled. If anyone can help me that would be appriciated. if anyone needs any thing else to help I will deliver. My other classes seem fine and it is just this one. This happens when I try to move. my code for Room.getTile is here:
public Tile getTile(int x, int y) {
if(x < 0 || y < 0 || x >= width || y >= height)
return Tile.floorTile;
Tile t = Tile.tiles[tiles[x][y]];
if(t == null)
return Tile.floorTile;
return t;
}
and this has no way to return null. Is solid is just a return true unless it is overridden.
public boolean isSolid() {
return false;
}

Either room is null, or room.getTile(x, y) returns null. You haven't pasted the relevant bits of those, making it impossible to give more information.

How to make an object follow a mouse (java)

I need help with trying to make the circle in this program continuously follow my mouse's x and y coordinates.It does follow my mouse in certain points. I think this is due to the fact that i am using the slope between the two coordinates in my program. An example of the issue would be that it will go in the exact opposite direction and move away from my mouse if I am to the right of its x position. Can someone give me some guidance?

For some weird reason I cant move the rackets up having a Y less than 0 and I also cant move them down at ALL. Here is the other classes (Ball - Guy)
public class Guy {
public int x,y;
}
public class Ball {
public int x,y,w,h,ny;
public Image i;
}
The ball also stops upon touching the left racket. It does not go back. There seems to be an issue with the x+= ... lines of code. I added debug messages , the messages print but the coordinates dont get an update!
I believe there is some bug with the whole code - working on it a whole day , did not find any errors :/

The problem is potentially in lines like:
b.x += delta * .1f;
Where you are taking a float and adding/subtracting it from an integer. It is possible that the Java engine performs a cast on the float data to turn it into an integer, which will loose data, and could cause the program to be non-responsive.
Additionally, you may want to move some of that procedural code that you have duplicated many times into the classes to improve the Object Oriented nature of this program.

People can use their first person view to walk the library.It is fine in java mode,but when I put it in java script mode,the view has problem.So , which part of my code has problems so that it can not run on website?
Thank you very much.
