@EddieRich Wow thanks for your thoughts! I really appreciate it. I like a lot of the different ideas you had for that! That sounds like a pretty cool theme for sure and the actual game play isn't really that much different either. I had another idea from someone that had said maybe a water based theme where you move around in a boat and shoot some sort of enemies... but this idea is pretty original and I think it would be really cool. It is definitely a possibility!

This may not be the correct place for this type of question but if you know of a better forum for this question that would be great too!
3  Game Development / Game Play & Game Design / Asteroids Like Game Ideas? on: 2012-02-09 15:31:50
Hey! I am working on an Asteroids like game. I have all the game play set up and it is quite fun. It is the same basic idea as the original but with my own twist on the actual game play. I was wondering if anyone had any ideas for a different theme instead of just a little triangle that shoots lines at wireframe asteroids haha... I'm really open to anything and I am having a hard time coming up with new theme ideas. It can still be a space theme but just hoping I could get some ideas as I am about to start working on new graphics for it. Thanks!

Oh thanks that really explains it well. Glad I know how to do it now. lol

@pitbuller I think you have missed the point on your comment. I know what I need for my game. I am using bounding box collision to detect a collision and from there on out I only brute force the overlapping rects created by the bounding boxes until there is a pixel overlap at the same x and y coordinate. I have that fine. I was hoping to get some help to understand how to transform a 2D array by a certain value of degrees. Whether it be an Android solution or not. It is a necessity that I implement this in my game and I need it to be perfect for the game to be played properly. More importantly I am very interested in learning how to do this and also the math behind it.

I am not using any anti-aliasing to do the rendering. When I display an image on screen it is using the Android Bitmap object(which is very similar to the standard Image class when doing Java Graphics). The rendering is done via a Canvas object which in turn is basically the same as the Graphics2D class in standard Java Graphics. I am not doing anything other than calling a draw method on the Bitmap object via the Canvas. I currently have a 2D array of pixels that I retrieved from the Bitmap and what I am looking to do is as the image is rotated, I need to rotate the pixels in the 2D array to match the specific rotation.

I don't know if this helps at all. What do you mean by "Is the angle quantised?" Thanks! I appreciate your thoughts on this!

I do realize that the collision detection like this is going to hinder the performance a bit. But it only needs to occur if there is a bounding box collision so I really don't think that it will be that bad. And I have seen many android games that have implemented it and it works/looks great. I currently am not worried about animated sprites at all, that will be next.

Currently my game has some collisions that do not look good at all because it is not pixel perfect. I don't necessarily need it on all of the images either. Just one because it has a pointy edge with a lot of transparent pixels around it. It is quite obvious when a collision occurs that shouldn't.

I appreciate your thoughts @pitbuller I need to keep a lot of things in mind when doing this for sure.
8  Java Game APIs & Engines / Java 2D / Rotational Collsion Detection on: 2012-01-17 17:19:24
I am working on a game in Android and I currently have pixel perfect collision detection working. It first checks bounding boxes and if that returns true then checks the overlap of pixels. All works great except when I rotate my image. The collision detection is still using the old un-rotated 2d pixel array. So my question is how I should go about rotating the indexes of the pixels to match that of the current rotation of the image?

Thanks in advance, I find this subject very interesting to work on!
