An Asteroids-Like Shooter Called Core Shot

WIP games, tools & toy projects
#1

Here’s a link to a download of a jar.
A target shows up in the middle you need to shoot to move onto the next level.
Sometimes you need to shoot enemy ships for the target to show up.

-Use the arrow keys to move.
-A and D to rotate.
-Space to shoot.
-S to stop with air brakes around level 6 and W for a force shield around level 8.
-Sometimes you need to minimize and maximize the screen to regain control of the ship.
-You can save the level you are on with a save menu in the upper left corner.
-The last level, which is 10, is glitchy, but if you quit and restart the level it is fine.

Still working a bit.

If anyone knows how to upload a jar to a webpage, so you can just click a link to play that would be awesome.

Hello,

I think there is a problem with the downloadable file, the access seems not to be public.

#3

Ok, try now.

#4
  • Downloaded jar successfully
  • Typing java -jar coreshot.jar (With openjdk 11.0.5 2019-10-15)
  • Clicking on the “start” button
    ==> The two blue buttons get white, and I have the exception :

java.io.FileNotFoundException: D:\pics\blue_sound waves\music\ComTruiseUsurper.wav (The system cannot find the path specified)

#5

Ok I will fix that. It still plays right? Just without sound.

I think it plays if you just click the jar and don’t run it from the command prompt.

#6

You have hardcoded absolute file paths in your class files… this will definitely not work.

Yeah, just on the background music though. I am pretty sure I have the problem fixed. Try again, if you want.

#8

I turn on the game and clicked start. After a second or two I hear some music, then the UI goes blank. No errors in console :clue:

#9

Did you try to minimize and then maximize??

#10

Ah that fixed it. Game runs a little fast on my computer. I assume it’s not delta/timed or framerate capped?

#11

No, its not. It runs fine on mine. I might look into delta and framerate caps, especially if others complain.

Thanks for the feedback.

#12

I know it runs fine on yours, because you designed your game to run specifically for YOUR cpu.

#13

It does feel like the spaceship moves a little too quick. What kind of game loop are you using if updates aren’t capped?

#14

Its on a timer that updates every millisecond and the ship is set to move 3 pixels in any direction every millisecond.

I tried different combinations of update times and pixels moved but this seemed to work for me.

For example, the animation in the background is on a separate timer that updates every second.
