Yeah, I just found out. I'm getting some strange error here though, the game would load just fine through the jar file. I'll notify you when I'm done fixing this.

I have reverted my game to my older version. Unfortunately this version is buggier at some parts, and laggier, but at least it works now. I'm going to backtrack now to figure out what when wrong.

Alright, I reuploaded a new version that has significant improvement. However, there appears to be an error with Greenfoot on using file inputs from text files. I'll see if I can make Greenfoot allow writing text files in exported jar files.

That explains the tomatoes - finally! Great game. (And, no, applets -that is Java programs running in a web browser- are not allowed to write files. That's a security feature against malicious code.) Good job, Michael

Thanks mik for the tip. I've uploaded a new version, this version allows you to save your progress by clicking on the save / load button. Btw, there appears to be a slight glitch with the new feature, there are certain situations where save/load will causes the objects to appear in the wrong place. Just wonder, how do you tell java to look at a text file in root directory of the java applet?

A really good first game, but I have a few suggestions. First put the speed bar up to about 3/4 of the way up, it's a lot smoother. Second improve the ships movement so it's more like proper asteroids. The forward and back buttons could increase or decrease speed and the player is constantly moving by this speed. You could then try to make the players movement seperate from the direction of the ship. For example I could press forward, build up speed and start in that direction, then release forward, continue moving, then press left and turn 90 degrees but I continue moving in the original direction.

Another suggestion - when you die, why not make the ship invincible for a while and/or return to the centre? I just died 3 times in a row because it placed me right on top of the asteroid that kiled me the first time!

Really good game. The thrust feels a little bit unresponsive though, and the ship appears to lurch when the rocket flame appears/disappears - I guess the images are different sizes? You could consider using a separate actor for the flame (though you'd need to position it well).

Thanks davmac for the advice. I implemented the idea, and it worked great, in fact, it made the game much less CPU intensive. So thanks. Also, JL235, I've tried putting the speed bar up to 3/4, but it causes the game to become extremely speedy, so I guess the speed bar is different on different computers. That's why I allowed the game to have it's speed to be changed.

Nice game!!! Its really interesting, the Greeps are cool, i liked it better without the drifting and acceleration well thats my opinion.

Thanks, just wondering, how far do you guys get on this game? Is it too hard? Also, remember to read the on-screen instructions, because they give useful information that can help you win. This new fix should fix the random save/load bug that occurred sometimes. I think I fixed some other stuff too, please tell me if you encounter a bug though.

Great game play. I found a few little problems: - I died, and the score counter was counting up for a long time afterwards. You probably have to change the counter to count up faster (or update immediately) to keep up with the points you can get. - It said at the end: Greeps killed: 0 (but I think I did get some) Asteroids destroyed: 167 Space ships destroyed: 223 The last two numbers seem to high. I'm pretty sure I didn't get that many... Good fun playing, though!

I have the same problems as mik mentions. Well, the asteroids count might be right but the space ship count seems a bit too high. I got to level 8. I think the acceleration might be a bit too high, and that the turning speed should be a bit faster. And, I just discovered that you can fly backwards as well - seems a bit weird, and might not be necessary if you get the acc. and turning speed right.

Very fun game :D And I love the way you combined two different scenarios into one XD Very creative Other than what everyone else mentioned, the game keeps going after you get a Game Over and you become invincible lol I don't know if you did that on purpose or if its even that bad; it's actually kind of fun (I only got to level 3 D: )

Thank you! I have fixed those errors, slowed down the rocket, increased turn speed. I also added and easy and hard mode (as requested by my school friends), and brought back "no drift" mode xD. Tell me if any of you ever get to level 20... cause hopefully all the bugs are fixed so I can continue with the storyline. (BTW, there is a cheatcode... have fun ).

D: Noooooo! no more invincibility... I like your choice of easy or hard *steals idea XD* Do you take CompSci at your school?

aaaaaah, lvl 3...... T_T.. 2126 ....... i'm sorry but... how to submiting a scenarios ??? T_T i didnt find any links T_T"

Lol yeah the invincibility would give away the storyline a bit too easily.. The easy and hard idea was harder to implement then I thought at first though, one advice is that when you click on the easy/hard object, have it remove itself from world after it's done loading the field. you can sumit a scenario by first making a greenfoot gallery account, and then open up greenfoot, click Export > Publish. There, just enter in the login info for your greenfoot account.

I think there is a bug in the Hard mode now. When igniting the rocket, it seems like the rocket speeds up a bit in the direction the rocket is already drifting in (not the direction it is pointing).

thanks. Actually, the bug should be fixed now, but you have to remember that the rocket uses a vector class to move, so each opposite movement will take some time to go forward. I also added a two player mode cause some of my friends requested that. Enjoy! Also, just wondering, is the game too challenging/easy and enjoyable/unenjoyable, or just right? Sorry about the slowness of my updates; I'm currently working on another scenario atm.

Just a tiny bug, when you click the Two Player Mode, it says choose a difficulty but it's like overlaid on top of the Two Player Mode button with a bit of transparency. A few suggestions about the two player game: a bigger difference in ship colors for easier identification, firing in the direction of the other player makes the bullets pass over the other ship rather than disables your gun, and of course independant lives counts so one person can keep going even if the other dies (in this case you can add a powerup that would resurrect your friend or something of the sort). But overall WOW! keep up the awesome work ^^,

Awesome scenario :]. Note: after death in two player mode, the dead ship sits around and draws fire forever o_O. It helped me get to around level 17 though by vacuuming up the greeps (I miss being able to ggpwn everything with energy shot, heh). It also got really slow by then; at one point I clocked it at about one frame per two seconds. That might be just me though because I was fiddling with the speed setting trying to get it to run faster.

thanks guys! I fixed those eerrors, madd the ships color easier to see, fixed the two player mode button.. I'll look into the game lag in the later levels, I think i can increase the effeciency of the search algorithm.

>< Typo ("you"): "Choose your level: In easy, you there's no 'drift'," (and punctuation error drift", )

lol thanks for pointing out those errors XD. It's strange that I should make so many spelling / grammar mistakes. Lol Just wondering, is the energy shot too weak/strong? Anyone got past level 20 yet? If not, I'll have to make this easier.
