Apps HAC demo lunar lander

[Malkoma]

HyperNext Android Creator is an easy to use software creation system that allows almost anyone to quickly start building their own Android apps that work. With HAC there is no need to learn Java or the Android SDK and it is much easier to use than Eclipse or Netbeans.

The latest update to HAC introduces a sprite surface allowing easy creation of sprite type games. New projects include a basic Lunar Lander game and Aquarium sprite demo. There are also extra screen commands and the ability to direct some graphics commands to the sprite surface. This update has focused on improving the graphics speed on both low-end Android devices and emulators. The memory system and interrupts have also been improved so making apps even more responsive when in front and very low lag when in the background.

In all there are 47 new commands and functions covering sprite animation, screen canvas and network.

HAC has also received a number of improvements including the option to make controls invisible at startup. The About Box and Splash Screen designers have been removed as the Home card is the natural place for having a Splash Screen or About Box.

A free trial of HAC is available on our website that can build then run apps on both Emulator and Android devices. It has full functionality except apps can only be signed by the debug key and they time out after a few minutes.

Visitors can also download some demo apps including Lunar Lander straight onto their Android device. Each demo also has a description and screenshot.

I was looking for code examples of modding Lunar Lander and saw this post but most of it is about HAC and absolutely no description of what makes this Lunar Lander different from all the others out there.

I'm not sure, but does it use sprites or does the user just draw a bitmap to a canvas as in the standard Java Lunar Landers? if it is really sprites then that would be cool and save a lot of work in writing more complex games. With no code to help judge this its disappointing - guess I'll have to Google this HAC stuff as there are no web links either.

Sorry for the missing code. I'll put some below, enough to give an idea how this version of Lunar Lander works. There is a full project on our website but it needs HAC installing in order to examine the code.

Yes it does use a sprite for the ship and this is drawn on an animation surface. A canvas could have been used and an image of the ship drawn on it but as you say sprites do offer some advantages such as handling occlusion etc.


Here is some code for Lunar Lander that I posted in some other forums a few days ago. Its not the complete code because some is in buttons and other controls plus initialisation code not shown here.

The Animation event is equivalent in some ways to a Game-Loop. It fires every 30mS or whatever is specified when the Animation is setup.

Add pullGravity to deltaY

if fuelNow>0 then
    Call KeyAction

Call DrawSpeedGauge

if firingFrames>0 then
    Decrement firingFrames

    SpriteFetchBank(spriteID,shipPlain)

Add deltaX to shipX
Add deltaY to shipY

SpriteSetCoords(spriteID,shipX,shipY)

Just to make the clearer about the demos. The demos are simple .apk files and are on our Projects web page. Just go to there using your Android's web browser and touch the green arrow next to the app/game you want to try out. The blue info graphics gives a screenshot of the app/game.
