Move a ball on mouse click in Java

阅读更多关于 Move a ball on mouse click in Java

问题 I'm trying to create the classic Breakout game as part of my programming assignment. I have to start moving the ball on a mouse click from the user. So I'm using a mouselistener to achieve that. The code below is just a smaller, simpler version of what I'm trying to do. But it does not move the ball in gradual steps. It just displays the ball at it's final position after the while loop is done executing. import acm.graphics.*; import acm.program.*; import acm.util.*; import java.applet.*;

Brick Collision Java [closed]

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 5 years ago . I have been working on a Breakout game and have just about everything done except for the brick collision. The ball bounces of the wall and paddle fine, but when it comes to the brick it goes straight through them. I'm pretty sure the problem is in the checkBrick() part of the

Assigned access application exits when Ctrl + Alt + Delete is pressed.

阅读更多关于 Assigned access application exits when Ctrl + Alt + Delete is pressed.

问题 I have set up assigned access on windows 10. The breakout key is currently set to ctrl + alt + delete (the default). However it seems as though when this breakout key is used that the application exits? Is it possible to keep the application running i.e. essentially switch user instead of log off? 回答1: You can set larger time-out period in registry To sign out of an assigned access account, press Ctrl + Alt + Del, and then sign in using another account. When you press Ctrl + Alt + Del to sign

How to make rect from the intersection of two?

阅读更多关于 How to make rect from the intersection of two?

I'm working on a breakout clone and I've been trying to figure out how to get the intersection rect of two colliding rects so I can measure how deep the ball entered the block in both x and y axis and decide which component of the velocity I'll reverse. I figured I could calculate the depth for each case like this: But if I had the intersection rect than I woudn't have to worry if the ball hits the block from the left/right or top/bottom (since I would be only reversing the x and y axis respectively), thus saving me a lot of typing. I've looked on Pygame's docs but seems it doesn't have a

Unity - how to use Vector2.Reflect()

阅读更多关于 Unity - how to use Vector2.Reflect()

I have looked everywhere including the Unity documentation but cannot seem to find any good examples of how to use Unity's Vector2.Reflect() function. I am trying to use this to control the direction of the ball (in a 2D Breakout game) when it hits a wall. It takes 2 arguments (inDirection, inNormal) but I cannot seem to figure out how to use this. Any help would be appreciated. Vector2 Reflect(Vector2 inDirection, Vector2 inNormal) : inDirection : black arrow inNormal : red arrow return output : green arrow The inDirection should be the velocity of your ball and the inNormal should be the

阅读更多关于 .BAT break out of multiple nested loop, after finishing the respective list

I know breaking out of a nested loop is fairly easy, however, I'm not sure how to do it when I'm working with multiple lists of servers. Here's the scenario: Goal: Search for sessions on a server matching a specific user ID, and also kill any disconnected sessions found Problem: I have multiple lists of farms. I want to cycle through the lists until I find the users session, and then stop when that list is finished (not stop when the session is cleared, they may have multiple sessions in the farm). Farmlist1.txt farmlist2.txt farmlist3.txt If the session is found in farmlist2.txt, I want to

Testing if colors equal

阅读更多关于 Testing if colors equal

I'm working on the Breakout assignment from the Stanford lectures on iTunes U (still pretty green) and ran into a snarl. I'm trying to set a point value for the different colored bricks so I can calculate a score but my if's don't seem to work. I have a feeling that getColor() isn't returning the value that I think it is; I created a status label to show my what it's returning but I still can't figure out how to test for that. More than likely it's something simple I'm missing or just don't know of yet. Here's a snippet of the bit I'm working on: if (collider != null && collider != paddle) {
