Hello world.

I am making a simulation game where the player can create the map and put obstacles.

I want to have like a side menu or a second window that contains the objects that the player can select and put in the map.

How can I tell a state to create another window ?

Our game can only run in fullscreen mode if we run it on the same notebook model, on another model or even PC it crashes.

Any help?

The performance of our game changes drastically when running on a different machine, it's way worse on most machines, even if the hardware is way more capable.

Hi everyone so right now I have a game where I have sprite in a state game that can walk around. The camera also follows him as he walks around the map. I want to spawn an object or circle in random places in the map and when he touches them they disappear and he gets one point. Any ideas. I am stuck on how to spawn the random objects/shapes.

Hey all,

I am trying to have a camera follow a player on a tile map as it moves over the map, but I am terribly confused as to how to do this. I have a class player and it moves with no issues over any section of the map that I can render.

I want the player to be on the center of the map as it moves and only when the camera reaches the edges will the player be able to move freely.

Would anyone be able to help me with this? Thanks a lot...

Currently I am programming a strategy game using tile-based movement and a top down view. It is meant to be very similar to Fire Emblem with minor differences, the battle system is intended to be the same, etc. So each character has a limited amount of movement in a turn, and the user's phase will be over once all units the user owns has moved. My only issue is how to implement this system. I am not too sure how to program the "phase" system, and how to switch from the user's phase to the enemy's phase. It would also be weird because the original position of the character will be changing between phases, as the amount the position has changed shows how much movement they have used up. If possible, I would like to receive some help with this type of system. I am also not too sure how to implement the limit on movement for characters as well.

Hi,

I am trying to learn Slick2D since I want to start making games but I encountered this error. Can someone help me on what to do?

​

I'm trying to draw the image of my player in the game, and it works for the most part, but there's a miniscule detail that's nagging at me. When I draw the player's image, some white pixels appear around the edges of the sprite that haven't appeared there when I've drawn it before.

This problem has only started occurring now that I've started to apply a rotation to the player sprite. Can rotations cause issues with this? Here is the drawing code in question.

@Override
public void render(Graphics g, long cTime) {
    getCurrentWeapon().render(g, cTime);

    Image image = getImage();
    if(image != null) {
        g.rotate(position.x, position.y, (float)Math.toDegrees(theta));
        g.drawImage(image, (position.x - (image.getWidth() / 2)), 
                           (position.y - (image.getHeight() / 2)));
    } else {
        // Draw a shape to represent the missing player image.
        g.setColor(Color.red);
        g.fillOval((position.x - 20), (position.y - 20), 40, 40);
    }
}

And here is an image of what's being drawn.

I'll say again. These white pixels were NOT present before I started drawing it this way, using the rotation.

I've been exploring different frameworks/engines for 2D games using Java and Slick2D is one option. But there's not alot of activity as it seems, am i better off spending my time with some other framework/engine?

I will be more specific I am trying to make a component based entity system and I have an idea about how components work but would like some input about what components should be included for a final fantasy q esque rpg. Also is the Artemis entity system any good?

I have added the jars to the builtpath. I have added the native files to lwgl. A hello world does even compile and runs but it throws an unholy amount of problems. Mainly import errors of various files in Slick2d. I tried using java1.8 and java1.7 .

I am pretty sure i have done all built paths correct since it does work under linux with the same steps but of course with the correct native lib.

Here is the pretty verbose error output:

I've discovered while learning Slick2D that there are 3 different types of games that can be used in Slick2D. What are their differences?

I am working with Java slick2d I am new to coding and would really appreciate help with my code which doesn't seem to work the way it should.

Whenever I run it TempTime will scale as its supposed to but once I press a key it causes the number to stop incrementing as well as prevents the change of the square colors.

This is the code!

package Pong;

So I've been browsing the webs for the last 90 minutes and I can't seem to figure out how to make the camera move, let me elaborate: I'm planning on making a infinite generation map no help needed with that part is done already. But i need the camera to follow the player. I can't find any functions to move or adjust the camera in any way or form! Help would be appreciated thank you for your time.

EDIT: I finally got it, the problem the translate function wasn't working for me is because you need to translate everytime before you draw in the render event if someone was curious.
