I'm trying to make a class called "Sprite", which is supposed to handle spritecards and such. However, I can't seem to be able to get the image height without having an image observer object.
Do I...

I'm using the drawImage(); method in Graphics2D to draw my png images. However, I'd like to be able to render them with screen blending. If it's possible, I'd really like to know how you do it, and...

It works now, thanks!

Anyone?
I'm really stuck right now and won't get far if I don't solve this issue. :(

I have a Player class, a Weapon class and a Projectile class in my applet game.

The weapon class uses Projectile objects when fired.

For example, everytime I click I want this code to execute:...

For example:

package topdowngame;
public class SpeedDir {
double speed;
private double direction;
static final SpeedDir INTERNAL = new SpeedDir(1,45);
// Other stuff

I am currently writing a weapon class and a projectile class, to use in a top-down game.
However, I can't seem to be able to load images in a class. It works in the main function, where I do it like...

I don't know if you should mark it as solved yet; I haven't fully tried this out yet as I've been very busy lately.

Okay, it seems like NetBeans had removed the images.
Anyway, I remade them and rewrote the angle system.
Now the lines also show their normal:

Thanks!
I have another question.
I am using netBeans. I've always run the file by clicking "Run file" when the Main class is selected. But now I accidentally clicked "Test Project". The applet...

Okay, I have a few questions.
What exactly is xDirection and yDirection?
Is this the kind of angle values I need for the slope angles?

Thanks alot for all the help!
I'll be sure to try this out when I have time.
I'll let you know how it went and if I run into any more trouble.

The character I currently have is just a small circle. Right now I don't really want to get the animations of the character itself to look good, I want it to work gameplay-wise.
This is what I have...

Thanks!
My main issue is moving up and down slopes. I really can't get it right.
The realism I want is pretty much only falling and sliding. The rest will probably be modified to better suit the...

I'm making a Java applet that's a 2D platform game.
Each map contains (So far) only collision lines, a background and a foreground image. The collision lines are used for collision detection with...

It seems to work, thanks! :)

After I've been running my program for a while, it freezes and gives me this error in the console:

Exception in thread "Thread-4" java.lang.IllegalArgumentException: timeout value is negative

Okay, I will!
Thanks again for the help.

Thanks!
It isn't actually a homework assignment, it's a personal project :)
Anyway, I believe I got this working, thanks!
I have a few other things I could use some help with though, and it'd be...

Do you think you could show me where I would insert that code?

But that can't possibly be the most effective one, can it?
It doesn't keep itself on a regular time pattern, it's relative to the amount of time the loading and rendering took.

I don't get where to insert the code and such; I could really use some help with this. :)

Here's my java file: (I removed irrelevant stuff)


package projectprojectile;
import java.applet.*;...
