The issue with your code is likely related to the getResource() method. It returns null when it cannot locate the specified resource. Update Resource Path: In your project structure, the images (flappybirdbg.png, flappybird.png, etc.) are directly under the src folder. When using getResource(), the paths should be relative to the src folder. Fix the code like this: java Copy code backgroundImg = new ImageIcon(getClass().getResource("/flappybirdbg.png")).getImage(); birdImg = new ImageIcon(getClass().getResource("/flappybird.png")).getImage(); topPipeImg = new ImageIcon(getClass().getResource("/toppipe.png")).getImage(); bottomPipeImg = new ImageIcon(getClass().getResource("/bottompipe.png")).getImage(); Note the leading / in the paths-it denotes the root of the src directory. Explanation The issue occurs because getResource() looks for files in the runtime classpath, not the file system. If the path doesn't start with /, it is treated as relative to the package of the current class. Using a leading / ensures the path is absolute within the classpath.

this video really motivated me to learn object oriented programming, thanks for the video, the only think i didn't like it was that you didn't want to properly explain the collision function, was it so hard to let others understand?
@KennyYipCodingАй бұрын
I make a lot of videos that use the same collision formula. If I had to properly explain the formula every time it would be tiring. I’ve already explained everything else and as mentioned in the video, the formula checks the intersection between 2 rectangles. If you want to understand it like an engineer, you’d analyze what it does by drawing two rectangles to see how it checks for intersection. Could also look it up since it is a formula.

Hey man, i really appreciate your videos, i'm learning alot from them! However i think your collision method assumes that the bird is a rectangle, am i right ? Can you please explain the logic of how you would implement the collision method to make it more precise 🙏
@KennyYipCoding5 ай бұрын
So the concept of collision detection of 2D games is based on the ideal of hit boxes, which is basically a rectangle surrounding the player. It would be too difficult to get the precision down to each individual pixel. The image itself is a rectangle and the empty space is part of the image. What you can do is create another X y width height for a new hit box bird instead of using the actual bird image dimensions. This hit box would essentially be a smaller rectangle.
@KennyYipCoding5 ай бұрын
Another more complex solution is to divide each part of the bird with different rectangles. One for the wing, one for the head, one for the beak. And then you would loop through each hit box and do a collision check. This would be used for if you had let’s say a street fighter game, for each arm and leg, there would be a separate rectangle for collision detection since the characters are much bigger, there would be too much empty spaces in the images to just check one rectangle for the entire image.
@TheBearCoder5 ай бұрын
@@KennyYipCoding Thanks for the response ❤ I'm going to surround the bird image (the black corners) with Rectangles and also add Rectangles on the pipes. Then i'm going to check if the bird corners collide with the pipes. But i'm not going to check weather the bird corners collide with the pipes all the time but rather only when the bird is close to the pipes (which is when the collision method that you implemented on this video is true). What do you think about that idea?

Because in 4 of these youtube tutorials concerning creating games in Java, most the varialbles are declared package private. Is encapsulatimg variables to private over exaggerated of these instructors? Your feedback is much appreciated and helps me to get a better understanding.
@KennyYipCoding7 ай бұрын
Generally it is good habit to make a data member private if it doesn’t need to be accessed outside the class, and const if the value will not change. But this is something you can do when finalizing code changes and cleaning up. For the game tutorials, I generally ignore this because I want to focus on the concepts and thought process of game programming and avoid any syntax nitpick !

Hello! Today (11 May 2024) the game seems to be very hard and sometimes impossible to win: pipes are placed very near horizontally and sometimes empty space between two pipes does not connect contiguously to the empty space of the horizontally following two pipes. Could it depend on the random components that today make it be so hard? In particular, yesterday all was normal and playable, both in my pc and in your website, and today the same issue there is both in my local run and in the one in your website.

@KennyYipCoding5 ай бұрын
well you have to understand why they don't work on mobile. It's just not in the code. You have to write the code to make something work. Theres no key being pressed on your phone, no space bar being pressed to make the flappy bird jump. There's no arrow keys being pressed to move the 2048 tiles. You would have to implement buttons on the web page to process these events. Also mobile web pages don't support drag and drop ui components well. There's probably a library or something out there that you can use to process drag drop events. In general, a laptop is not the same environment as a mobile phone, so a website would function differently. That's where mobile apps come in. If you want to make a game playable on the phone, it would have to be a mobile app, which is out of the scope of these tutorials. Nobody plays mobile games on a website, they play through applications. 🙂
