Hi There,
i have an Question about Sprites.
I would use an Image for Levelgraphics so my Player Sprite (with Physic on) can use this as Obstacle.
As Sprite it does not function. Must i draw the Level Sprite by Sprite to have Obstacles?

Greetings
Kai

You should be able to create a sprite, turn physics on for that sprite and then set its shape. I'm not quite sure what your question is (sorry), can you explain in a little more detail and perhaps give an example of what you are trying to achieve?

I try ... but my english is not sooo good.

also ... i have an Image . This is my Level Image with Transparent background.
Than i have an Image for the Player
i want that the PlayerBall move over the Level Image. That is no Problem.
But ... When i Set LevelImage for Physics on and PlayerBall too ... the Playball ist not seen.
Do u know what i mean?
My Question is now can i have an Levelimage with bounderies/Obstacles where the Playerball can not move throug?
Or must i make the Level sprite by sprite for Obstacles?

I hope that was a little bit clearer ...

Greetings
Kai

I'll add my answer from your other thread here:

You won't be able to use one image as a physics-enabled level. You could still use it and add transparent sprites as static physics objects over the top.

It's a nice idea - a well-drawn background with invisible physics sprites. The disadvantage though is that you can't reuse your drawn platforms etc throughout the game.

I have borrowed a picture to demonstrate. Here, the picture is one background image with NO PHYSICS. Next, I have drawn boxes where you would need to put static physics boxes where the platforms and obstacles are, to create your physics world. BUT it is much better to create your background from separate objects.

Actually it is possible to use a single image and add many physics shapes to your single sprite but it isn't the easiest method or the best way to use resources as BatVink says.

Of course, my very bad! I never thought about having disparate shapes on the sprite. I've always used multiples to form a more complex solid.

Me too but i suddenly thought of a number of ways this might be useful for the right game (such as a pinball machine game)

HUH? WHAT? Where?
Did someone say Pinball??

Quote: "Actually it is possible to use a single image and add many physics shapes to your single sprite..."

Well, are you going to tell him how, or just tease him???

I would tell him how, but I used basic methods (as above) for my Pinball WIP. (setting bumpers to a circle shape of course, not square)
I would love to see more Virtual Pinball Machines made with AppGameKit!
As well as other retro non-electrical and mechanical electronic games, like the one he is working on.
It looks like those little boxes that had a ball in it and you had to roll through the maze avoiding all of the traps (holes) to win.
Gyroscope and a steady hand would come into play here.

Well using the SetSpriteShape... and AddSpriteShape... commands you can add circles, boxes and convex polygon shapes to any sprite. As many as you like.

I could write a great long example but I honestly don't have the time, I would just suggest that if anyone wanted to have a go at doing it that way they should look at the help files for sprites.

The first shape should be made using SetSpriteShape... (where "..." is Circle, Box or Polygon) and the rest using AddSpriteShape...

Remember also that your sprite needs to have SetSpritePhysicsOn for this to work too

having trouble wrapping my head around the physics involved for the AddSpriteShape(), so I have been avoiding that in fear of running into trouble.
Guess I better start experimenting with it, in case I am missing out on a major improvement.

Thanks
