So instead I found a substitute called QuickBox2D which is a library built on top of Box2DFlashAS3 which makes everything a lot easier as well as adds a couple more helpful features. But on top of that the creators website has LOADS!!! of examples of the engine working which makes it so easy to learn from references.

So check it out if you are looking to learn an AS3 Physic Engine as it is definitely the easiest to pick up and play with. Also here are two examples to compare APE and QB2D.

QB2D-Demo

…But anyway after much frustration I’m finally making head-way with learning a AS3 Physic Engine called APE (Actionscript Physics Engine).

So far I’ve just been getting to grips with the engine by messing around with demos and creating my own. But I was thinking a physics based puzzle platformer or PPP as I like to call it would be interesting.

So anyway this is what I have so far and is just a short demo:

Also you’ll be happy to know I’m still working on EvoCannon 2 but I’ve come across a hitch/bug that I’m trying to solve right now with help from the kirupa.com forums. Lastly I’ll conclude with some up and coming info; I’ll be running the 3DMark Vantage benchmark on my PC today and then posting the results. Then I will be installing Windows 7 shortly after, and then running the benchmark again so all you techies can see if it really makes a differences to the performance of your PC.

• Enemies now drop money instead of bullets (Used in the upgrades shop).
• Money gravitate towards the player.
• New Health Regneration System.
• Bullet limit (A limit to how many bullets can be fired at once).
• Grid based level selection such as:

|01 | 02 | 03 |04 | 05| (All the ones along this line have arena design 1)
| 11 | 12 | 13  | 14 | 15| (All the ones along this line have arena design 2) you get the idea.

• Cannon Customization (New weapons and upgrades)
• Primary Weapons (Changes the look of your ship):

1. Cannon (1 Bullet on-screen, 4 Bullets on-screen, 8 Bullets on-screen)
2. Machine gun (Low accuracy, Medium Accuracy, High Accuracy)
3. Beam (Small width/lasts  1 second, Medium width/ lasts 2 seconds, High width/ lasts 3 seconds)
4. Shotgun (Small spread, Medium Spread, High Spread)

• Secondary Weapons (Switched through the use of the F key)

1. Rocket (fires one big rocket, big splash damage, long charge time)
2. Mines (drops a random minefield around your ship, you can’t hit your own mines, long charge time)
3. Bomb (Causes everything with a certain radius to explode, long charge time)

• Passive Upgrades (Constantly effecting your ship):

1. Better Regeneration of Health
2. Shield Upgrades
3. Auto Protection Turrets (Automatically target and shoot down enemies)
