The first and biggest thing that I'm asking is that when anyone other than me and one other person runs a file that I made, it comes up with the following error. I have checked everything that I can think of, I'm really out of ideas.

The procedure entry point_invalid_parameter_noinfo_noreturn could not be located in the dynamic link library MSVCR100.dll.

While I'm here, I'll ask a couple of other questions. Firstly, how do you make parts of sprites transparent. e.g. You have a ball or something and you don't want it going around as a ball inside a white square.

Lastly, is there a way to somehow set the edges of, say a spaceship without having to put it in manually, and saying if the stuff is this far in this and not this far this way and so on.

Thanks

EDIT: I just had a look and with the sprites, could someone actually explain it to me, the functions that people write for it, although short, I have no clue what they are doing. For a start, what is alpha?

Hi

1. This is the famous MSVC runtime redistributables which are missing from the other systems. Which version of MSVC are you using?

2. You need to prepare the ball image with a transparent background, in a graphics program like GIMP or something, and save it as a type of image that supports transparency (like PNG).

3. Not sure I know what you mean but do you want to define the edges of a sprite (for collision detection or something??)

4. If you don't know what alpha transparency is, maybe you need to do a bit more learning before you tackle the code. Do some googling on it

Thanks

4. True...sorry

Hi

OK, so you need the MSVC 2010 redist stuff. Install these on your target machines, or (better in my opinion) static link your program - this requires quite a bit of work in SFML to recompile the libs, then change your project settings. Anyway the redist installer is here:

On collision detection, there are loads of posts on this forum about this topic, so do a bit of searching. You're not the first to ask
