I've ran into a few problems with my code. I'll highlight the errors in bold (asterisks **) :) Thanks in advance (code highlighted has this error: x cannot be resolved to a variable")
package com.cmnatic.reborn.gui;
public class Bitmap {
public final int width;
public final int height;
public final int[] pixels;
public Bitmap(int width, int height) {
this.width = width;
this.height = height;
pixels = new int[width * height];
}
public void draw(Bitmap bitmap, int xOffs, int yOffs) {
for (int y = 0; y<bitmap.height; y++) {
int yPix = y+yOffs;
if (yPix<0 || yPix>=height) continue;
for(int xPix = 0; **x**<bitmap.width; x++) {
int **xPix** = **x+x0ffs**;
if (xPix<0 || xPix>=width) continue;
pixels[xPix+yPix*width] = bitmap.pixels[x + y * bitmap.width];
}
}
}
}
Also, I've got an odd problem which I'm not sure about: (code below highlighted has the following error: "Duplicate local variable xPix"
for(int xPix = 0; **x**<bitmap.width; x++) {
int **xPix** = **x+x0ffs**;
if (xPix<0 || xPix>=width) continue;
Thanks in advance, CMNatic
xPix
is already defined within the scope of the inner for
loop. x
needs to be declared before it can be used so it makes sense to use
for (int x = 0; x < bitmap.width; x++) {
Also
int xPix = x + x0ffs; // typo
should be
int xPix = x + xOffs;
As always the error messages provide a meaningful indicator as to the nature of the issues...
x
is no where declared but being used in the loop, So the error. Correct your loop variable to x
for(int x = 0; x<bitmap.width; x++) {
int xPix = x+x0ffs;
if (xPix<0 || xPix>=width) continue;
All the problems will be solved.
