| | Hi guys, I want to paint multiple layers of images onto one image. I'm going to be using BufferedImage for this. How would I go about painting these multiple images onto one (in essence creating a new image. sort of like a collage)? Would i get the graphics context and … |
| | Hey guys I'm using JLayeredPane because i want three distinct layers in my program. terrain, buildings and then characters. I thought that JLayeredPane was easily the best choice for this context. The problem is, I have only seen people *adding* components to their layers. I need to do my own …  |
| | Hi guys I want to take an image and cut it into blocks, then store each block in an array of bufferedimages. I have tried many things [CODE]public void splitImage(int cols, int rows) { int w = thePic.getWidth()/cols; int h = thePic.getHeight()/rows; int num = 0; tileset = new BufferedImage[w*h]; … |

| | Hi, I just wanted to ask for some help considering images. What I would like to do is take an image and then split it up into blocks of a certain dimension (say, 20x20). Then I would like to put these blocks into a 2D array. I tried searching for … |
| | Hi I'd like to use an array to store values of particular things. I would like names to correspond to each value in the array. What I was thinking was, should I perhaps create 2 arrays: String[] and int[]. Then, when I call data from say example_int[1] I call the … |
| | Hi again What is the name of the component in programs where there is: a 2 character text field and on the side there are up and down arrows to increase or decrease the value in the text field. There is usually one in the "Print" dialog in MSWord, with … |
| | well, im not sure, but your code says [QUOTE]income = ITI1120.readInt( );[/QUOTE] and you declared income as a double. And provincial also relies on income for its value, so thats why it doesn't work. |
| | Hi, I want to build my own simple 2D RPG in Java. Whilst I am new to Java, I do understand the fundamentals of OO programming, and I am quick to learn, as long as someone isn't too impatient. I just wonder if there is anybody who can check my …  |

| | The else provides a fallback condition. Just a single if is there for one condition only. for example, if you put just an if in the code, it goes through one condition then continues with the code. with if-else, it checks the one condition, if that condition is not true … |
| | Well, add a method in the program which runs a batch file which can then compile for you. nobody is going to do this for you, don't demand us to do the project. |

| | Hi, I don't want you to do the project for me, but I would like to ask about the logic behind building an RPG in java. You would have to assign a picture for trees and houses and stuff right? Then would you create an array and assign each map … |
