Hey guys!

Over christmas I thought it would be fun to build a new Android game. This time it works on most handsets...

v1.06

- fixed some terrible bugs and added some new features

- Faster Shoop gains

- more enemy types

- laser eyes now works correctly.

check it out!

Here is the website:

http://www.longcatgame.com

Here is a youtube video showing the gameplay:

The game was built using only stackoverflow.com and processing.org as a code reference. Any problems I encountered were usually resolvable with the help of the processing forums or stackoverflow tags.

Why?

I originally intended the game to be a joke to put online over christmas where long cat collected christmas treats with his christmas hat on. But I thought I would turn it in to a full blown shooter for fun.

Creating a snake-like body.

[2 Replies]
- 04-Nov-2011 05:15 AM
- Forum: Programming Questions
I am basically trying to create an array of rectangles that updates its position continuously to form a snake like effect. The problem I am having is that by updating the position of each rectangle 1 by 1 is updating the position too slowly or updating the position of all of them using a for loop updates them to the same position.

Here are the initial variables:
1. int xArrayPos = 0;
2. int[] bodyY = new int[50];
3. int[] bodyX = new int[50];
heres the code for the bendyBody method:
public void bendyBody(){

bodyY[0]=catY+longcat.height-5;

bodyX[0]=catX+longcat.width/2;

for(int i = 1; i < bodyY.length; i++){

bodyY[i] = bodyY[i-1]+5;

}

// for(int xArrayPos = 1; xArrayPos < bodyX.length; xArrayPos++){

xArrayPos++;

if(xArrayPos == bodyX.length){

xArrayPos=1;

}

bodyX[xArrayPos] = bodyX[xArrayPos-1];

if(bodyX[xArrayPos] < bodyX[xArrayPos-1]){

bodyX[xArrayPos]+=10;

}

if(bodyX[xArrayPos] > bodyX[xArrayPos-1]){

bodyX[xArrayPos]-=5;

}

//}

}
here is where I am generating the rectangles:
for(int i = 0; i < bodyX.length; i++){

rect(bodyX[i], bodyY[i], 10, 5);

// Point(bodyX[i], bodyY[i]);

// curveVertex(bodyX[i], bodyY[i]);

}
Anyone know a good way to make it so that each rectangle updates its position one after the other in a snake like effect?

at the moment the if statement way of updating is too slow and the for loop is too fast.

I should also mention I only want to modify the bodyX[1] onwards values as the 'points' which are 'following' the bodyX[0] value.
Thanks,

Feedback on an android game. Jump 'n' Tilt

- Forum: Android Processing
A few months ago I made a game called Jump 'n' tilt for android using processing. I want to go back to it and develop it some more. I have been away from processing for a couple of months as I have been looking into oF BUT after the alpha release of 2 and watching the Eyeo festival 2011 video with Ben Fry and Casey Reas I have had a spark to come back to developing one of the games I put together!

I feel like there is alot more I can add to it now... I just want to get some feedback on what is wrong with it and how it can be improved.

The game runs quite slow on bad devices which I think actually... it probably should run alot faster... Im just not entirely sure on what techniques I can use to increase the load times.... (hence why im asking here for feedback and not android game enthusiast forums!).

Please could some of you guys give it a go and tell me what you think is wrong with.... what could improve loading times... what looks bad.... what looks good...

It has a scoreboard system built into it too so you can actually view your scores against other people in the world. Im sure that could also be improved but really... I dont think that is the main concern for me right now.

Erm....

Sorry for the wall of text.

Heres the link to my game:

https://market.android.com/details?id=processing.android.test.cube_boy&feature=search_result

Please give me some feedback!

Make it as critical as you can. I love that.

There is still a nullPointer when you try and check for the global scores but apart from that I havent received any other errors on the market so I think it is safe to post it here on the exhibition forums... here it is:

https://market.android.com/details?id=processing.android.test.cube_boy&feature=search_result

I rate this mild as it contains questionable items to collect. if you play it with your wifi turned off you will be able to read the full text without the adverts popping up.

please let me know if you get any problems and more importantly... let me know what is not fun about it!

cheers guys! ;)

All with revision 0198. I couldnt run ant with 0199 because of the classes.dex (it said something like that).

i can share the games source if that helps (its a monstrously big game and youll probably put your palm over your face when you see the code).

edit: i have taken off the nullPointer that was originally here as I have figured that one out ;P.

going on a family trip today as well so I will bring my code with me and see if there is anything noticeably erroneous in the code that could be causing it whilst I am out. It is the same game from the original post i made ;).

cheers :)

I noticed that in the 0198 revision there is a new thread function added?

+ Addded thread() method that takes a function name as a parameter,

and runs it on its own thread. No more classes!

This looks really useful. do i just call thread(myFunction()) and thats that?

:o. can someone give an example of this :P?

Quick Way to scale dimensions to the screenHeight

[1 Reply]
- 23-Jun-2011 03:57 AM
- Forum: Android Processing
Hi guys... Basically I created this game here:

https://market.android.com/details?id=processing.android.test.e1

The problem I came across is scaling of typography and imagery to different screensizes as I wanted a universally hard gameplay.

so..... heres my (maybe) solution... nothing hard... just one function....

lets say you set the fontSize to 30 so:
1. textSize(30);
and you have 2 phones... one with a screenHeight of 480 and another with 600...... how do we solve the problem of scaling?

this is the function i used to solve this issue and scale it on both phones:
1. int scaleStuff(int newSize){
2. newSize = screenHeight*newSize/<size of screen you are developing on>;
3. newSize = int(newSize);
4. return newSize;
5. }
and then:
1. textSize(scaleStuff(30));
Anyway... I think this can be improved..

Im sure there is a more developed solution for scaling but thats the best solution I could come up with!

thanks,

UPDATE:

Heres a more developed version that will work with either floats or integers
1. // my sneaky scaling system for android.
2. int scaleStuffByWidth(int newSize){
3. float scaleSize = float(screenWidth)/<screen_width_size_you_are_developing_on.0>;
4. float tempSize = newSize*scaleSize;
5. newSize = int(tempSize);
6. return newSize;
7. }
9. float scaleStufffByWidth(float newSize){
10. float scaleSize = float(screenWidth)/<screen_width_size_you_are_developing_on.0>;
11. float tempSize = newSize*scaleSize;
12. newSize = tempSize;
13. return newSize;
14. }
16. int scaleStuff(int newSize){
17. float scaleSize = float(screenHeight)/<screen_height_size_you_are_developing_on.0>;
18. float tempSize = newSize*scaleSize;
19. newSize = int(tempSize);
20. return newSize;
21. }
23. float scaleStufff(float newSize){
24. float scaleSize = float(screenHeight)/<screen_height_size_you_are_developing_on.0>;
25. float tempSize = newSize*scaleSize;
26. newSize = tempSize;
27. return newSize;
29. }

APWidgets, APVideoView question

Hi guys!

I have a question regarding APVideoView...

I understand that video files can only be loaded from the SD card to be played back... I just wanted to put a game intro video in and small demonstrations throughout the game. how would I go about loading mp4 files that should 'come with the game when its installed'. as opposed to loading them from the card... (or copying them to the SDCARD on install and playing them if they are detected; just incase the user deletes them).

or is there a solution to this problem?

heres my code:

import apwidgets.*;

import android.text.InputType;

import android.view.inputmethod.EditorInfo;

APWidgetContainer widgetContainer;

APToggleButton toggleMusic;

APToggleButton toggleTheme;

APEditText nameField;

void initWidgets(){

widgetContainer = new APWidgetContainer(this); //create new container for widgets

toggleMusic = new APToggleButton(10, 200, 100, 70, "Music"); //create new toggle button from x- and y-pos. and label.

toggleTheme = new APToggleButton(10, 400, 100, 70, "Space");

nameField = new APEditText(20, 100, 150, 50); //create a textfield from x- and y-pos., width and height

widgetContainer.addWidget(toggleMusic); //place toggle button in container

widgetContainer.addWidget(nameField); //place textField in container

nameField.setImeOptions(EditorInfo.IME_ACTION_DONE);

// nameField.setImeOptions(EditorInfo.IME_ACTION_NEXT); i switch to this to see if itd work.

toggleMusic.setChecked(true); //toggle button is on from the beginning

}

void runWidgets(){

if(toggleMusic.isChecked()){ //if the toggle button is on

}

pushStyle();

fill(255);

text(nameField.getText(), screenWidth/1.5, screenHeight/5); //display the text in the text field

popStyle();

}

so ermm..... why isnt the done button working on the popup keyboard :P? has anyone else experienced this problem with APWidgets?

The other question I have is..... does anyone know how to make the buttons hidden?

lol im so failure with this library :D

Hi guys!

I was looking for a way to create a quick global score system.

The only thing I really know about web coding and databases is how to use a CMS...

I did some research and the best option I could find was http://scoreninja.appspot.com/ ... (but i dont really know how to use it within processing)

anyone who has implemented a global score system for android before or if you could help?

I nearly have embedding working so after my exam tommorow morning (GMT) I will post (hopefully) an embedded version of the game to try out. We havent finished putting in the scoreboard and menu system yet but when we've done that i'm sure itd be fun to play!

Here is the video link.

http://www.jaboston.com/2011/04/shaft-alpha-v01/

It uses openGL and Matthew Yee-King and Martin Roth's AudioThread classes for the sound interaction.

The basic concept is generated cubes. I am playing with the camera angle here to generate the walls.

The walls are generated by drawing an array of squares (imagine you are looking from birds eye view) and then changing the camera angle so it looks like a floor, walls, or ceiling.... then rotating the camera by 90 degrees to generate the next wall.

A quick understandable way to show u what i mean is this code:

rotate(90);

drawWall();

rotate(90);

drawWall();

rotate(90);

drawWall();

The size of the rectangles and position is determined by the music. The Color also switches at different intervals and a threshold is in place for sudden flashes of light (aswell as the rectangles size changing).

This was another first year project at my University which is actually a group Project devised by: Callum Pywell, Joseph Boston (me), Ondrej Kruzica, Jack Wooster and Michael Gray.

Im just wondering if anyone has figured out a way to do all of this within processing? or if anyone has came up with a couple of simple audio classes? Or peoples experience with playing with sound. I tried the method mentioned here:

http://realmike.org/blog/2010/12/11/sound-playback-in-processing-for-android/

It kept getting errors and I couldn't quite figure out why.

Has anyone figured this out? just for sound sample playback or even just generating noise.

cheers,
