B4A Library Game Sprite Library

Hi all,
This is my first attempt at creating a library so I hope it works.
It is a heavily modified version of the code Erel kindly posted for his GameView library.

03/02/2014 - v0.1
First Release
04/02/2014 - v0.2
Added FPS code to the GameSpriteView
12/02/2014 - v0.3
Removed the list-based system replacing it with a sub _Draw() call instead. Also added a convenient DrawText() command. Useful for displaying basic text messages (FPS monitoring).
16/04/2014 - v0.4
Changed: AnimDelayRate to AnimDelayTime. Now using milliseconds for timing.
Added: Filter to the Sprite class
Added: DeltaTime to the GameSpriteView class


GameSprite Library v0.4

GameSprite a very light-weight (10K) library designed with 2D games creation in mind. As the name suggests the library is geared towards sprite handling with a simple to understand command set.
The library features a powerful one-call animation command to set up automated animation.

Hardware acceleration is supported.

The key features are:

• GameSpriteView - the main display supporting virtual screen sizing, global rotation, global anchor point , get FPS, get DeltaTime
• Sprite - A bitmap-based object with positioning, anchor, size, flip, rotate, colour, alpha, animation, region support, basic collision (overlap) checking, and distance checking.

GameSpriteView methods and variables

IsHardwareAccelerated()
VirtualDisplaySize() , VirtualWidth() , VirtualHeight() , VirtualX() , VirtualY()
Anchor() , AnchorX , AnchorY
DrawText()
Rotate
FPS
​

Sprite methods and variables

Bitmap
Position() , X , Y , CenterX , CenterY
Size() , ScaleSize() , Width , Height
Anchor() , MidAnchor, AnchorX, AnchorY,
Rotate , FlipX, FlipY
AnimDefineCells() , AnimSequence() , AnimCellRange() , AnimCellNumber , AnimDelayTime , AnimNextCell , AnimPreviousCell , AnimPlay
Region() , ResetRegion , CopyRegion()
isOver() , Overlaps() , DistanceTo()
ARGB() , RGB() , Alpha, Filter
Visible , Copy() , Reset​

You can get the library here, which includes some basic examples you get you started.
Included in the zip is an updated Pocket Invaders, which is a fully playable game to show-case the library.

Also now available, a companion tool written in B4J called SpriteMotion for assisting in the process of defining sprites contained within a sprite sheet.

Hi Salvador, everything should be there. The Jellybeans demo needs 2 files - bkg3.jpg, jellybean.png
These are in the GameSpriteExamples > Files folder within the zip.
I have uploaded version 4.0a just in case there is an issue with the current zip.

Sub Button1_Click
    If birdAnimated.X < 50%x Then
            birdAnimated.Position(birdAnimated.X+gsv.Width*0.7,birdAnimated.Y)
            birdAnimated.FlipX=True
    End If       
    gsv.Invalidate

I am new to this animation. Trying to get the attached images to jump from left end of screen to right end vice versa depending on the touch of buttons. But not able to get smooth jump. Please guide me

Hello, do you still have the library source code?

 

[kdgarris]

Is this still available? The download link isn't working.

Has XUI2D not replaced it?
