Need help getting a picture to flip in Java. How do I do it? Here's my code
* Horizontal flip method
* In this method, I've given you the basic structure of how things will look. There are a few incomplete assignments inside of the method. It is your job to figure out how to complete those assignments!
* This method works almost like the horizontal mirroring method you saw in your text book (pg 135), but instead of mirroring on the middle of the image, we want to flip it all the way.
* Hint: Why do we need tempColor in this case? I encourage you to reflect on this question if you find your method not working the way it should!**/
public void flipHorizontal()
{
Color tempColor;
//FILL THESE OUT AND THEN UNCOMMENT THEM!
int limit1 = this.getHeight();
int limit2 = this.getWidth();
Pixel leftPixel = null;
Pixel rightPixel = null;
for(int i = 0; i < limit1; i++)
{
for(int j = 0; j < limit2; j++)
{
leftPixel = getPixel(i,j);
rightPixel = getPixel(limit2 - 1 - i,j);
rightPixel.setColor(leftPixel.getColor());
//FILL THIS OUT AND THEN UNCOMMENT IT!
//tempColor =
//After you store away your pixel colors...call setColor() here on the appropriate pixels and flip the picture!
}
}
Shit's definitely not working.

What did you do with tempColor?
If you're still confused:
Imagine you have strings stored in variables a and b. How would you swap the values?

I didn't do anything with tempColor, and I'm honestly not even sure why it's there.
do I have to set tempcolor as variable a, then set a to b, then b to tempcolor?
>>46720
Yeah. Get yourself a rubber duck, son.

I'm getting this error when I try to run my code calling flipHorizontal.

Nevermind, I fixed this by using a different picture. Now I'm just having an issue of swapping the shit. I don't get it. Here's what I have:
tempColor = leftPixel.getColor();
tempColor2 = rightPixel.getColor();
leftPixel.setColor(tempColor2);
rightPixel.setColor(tempColor);
I've got no ideas.

If I leave one of them out, whatever side of the image is supposed to be flipped will flip (if I leave in right pixel it changes to the left side of the image), but if I leave them both in they just cancel each other out.
Bumping one last time for hope.

Okay, anon.
Imagine you have a glass of Grape Kool-Aid and a mug of Cherry Kool-Aid.
You decide the Cherry Kool-Aid needs to be in the glass, and the Grape in the mug.
So you pour the glass of Grape into the mug, and then you pour the mug of.... wait, that doesn't work.
You pour the mug of Cherry into the glass, then you pour the glass of.... wait, that doesn't work either.
Guess you'll need an extra glass.
tldr:
Object o; o=p1; p1=p2; p2=o;

tempColor = leftPixel.getColor();
leftPixel.setColor(rightPixel.getColor());
rightPixel.setColor(tempColor);
Isn't tempColor my third container in this case? But when I put in that code it just cancels each other out and nothing happens.
