Hi there
Can someone help me. I am using Gwin, and I cannot make a blob move down, or right on a page. However I can make it move left and up. What am I doing wrong?
Heres the code:

case GwinKeyNames::CURSOR_LEFT:

Gwin.setPenColour( GwinColourNames::WHITE );
Gwin.setFillColour( GwinColourNames::WHITE );
Gwin.circle( blobX, blobY, blobRadius );

blobX--;

Gwin.setPenColour( blobColour );
Gwin.setFillColour( blobColour );
Gwin.circle( blobX, blobY, blobRadius );
break;

If anyone could help, I'd be greatful. Making the Blob go up is easy, I just change it to blobY--;

I'm new to programming and am stuck... so please help

I do not know what Gwin is, but this may still help. If blobX-- moves the blob left along the X axis, and blobY-- moves the blob up along the Y axis, then it seems that blobX++ (or incrementing blobX) would make the blob move right, and that blobY++ would make the blob move down. You can also use other operators, such as blobY+=20 to make the blob move 20 points down, and blobX-=5 to make the blob move 5 points to the left.

However, like I said, I do not know of Gwin, and this advice is simply based on the generic math operators provided in C++.
