I wouldn't use that spritesheet. First of all, I don't think it's the real sprite sheet. I think it is just an example of what's included in the art pack. That's why the background is not transparent.

Typically with sprite sheets there should be a accompanying meta data file that tell the game engine the location of each tile on the sheet. Since I'm guessing this is just a generic image, it wouldn't include that metadata file. And more importantly, it most likely wouldn't be a spritesheet compatible with hyperPad any ways. hyperPad uses sprite sheets and metadata plist files compatible with Cocos2D. So anything for cocos2D should work with hyperPad.

The good news is, you can find most, if not all of those tiles in their original format on the original creators web site: https://kenney.nl/assets
We use Kenney's stuff for hyperPad because it's awesome and versatile :).

I sometimes download stuff using puffin

As Stephen says,
it looks like your emitter position is the problem. The emitter position is where on the object the bullet will shoot from.
Since in your case, it looks like the bullet is very close to the ground, when you have destroy on impact on, it destroys immediately because it's hitting the ground right away.

You can enter values manually from the shoot behaviour properties, or you can tap the object graphic from the behaviour properties and move the blue target to the location you want the bullet to shoot from.
