Try compliling with g++/c++ instead of gcc.

Yes, more info, show some code, explain why pressing left doesn''t have the effect you expect. Possibly start a new thread as this is now a different topic to the original.

Although, saying all that usually I find that once one problem is dealt with another immediately raises its ugly head. It''s tempting to immediately go and say to the last person who helped ''I''ve got another problem now'' without spending a lot of time thinking about it or really trying to establish the cause of the trouble.

Look at it a bit longer to get to the root. Write out an explanation of how you think it should be working and why the code you''ve written represents that design. You''ll (hopefully) find somewhere that it doesn''t match up. Even if you don''t understand how to make it match you''ll have narrowed it down and will be in a better position to explain it to us.

Peace

To little detail here. But one guess is that you are changing your variables inside a function

MakeMovement(x, y);

MakeMovement(float x, float y)
{
//Do something
}

This code only alters the local variables you need to use pointers to affect the variables you send in.

Wild guess....
