Interesting Problem with X and Y Values...

When I try to use the same variables for drawing two different images on the screen, the images appear in different places. I have not changed the handles, and the images are being drawn one after the other with no other code in between. What are the possible reasons for this? |
| ||
Can you post some code? |
| ||
I'm not sure which part of the code could be causing the problem, and I don't want to post the whole 15 KB program. The code that draws the images on screen is:DrawImage pathcorner4\image,x,y DrawImage pathcorner2\image,x,y The error probably is not there, though. Should I post the rest of the code? |

After rewriting some of the code, I have managed to get everything where it is supposed to be. However, I do not know why I had to add something to the x and y values in certain instances. Here is the function: The line DrawImage pathcorner1\image,x,y is drawn correctly without the adjustments to the x and y values the others seemed to need. On the other hand, in the lines DrawImage pathcorner1\image,x,y y = y+ImageHeight(pathcorner1\image)-5 x = x+ImageWidth(pathcorner1\image) DrawImage pathsegmentV\image,x,y pathcorner1\image is supposed to have the same x value as pathsegmentV\image, yet they do not appear on screen with the same x value unless ImageWidth(pathcorner1\image) is added to x. |

Are you sure you haven't used ImageHandle() or midhandle() somewhere in your code? |
| ||
I'm positive. |

I don't see anything when looking through quickly. It would help to have a fully working example if you could. If you post just the code, you can just state the image sizes and I can plug in something of my own. Edited the post above to ask about midhandle() as well. |
| ||
Here's the code in full: Sizes for the images in question are: pathsegmentH\image 480 X 131 pathcorner1\image 130 X 132 The other images are 90 degree rotations of these two. And no, I did not use midhandle() either. |
| ||
The other images are 90 degree rotations of these two. I suspect that this is your issue. AFAIK using rotateimage will rotate the imagehandle also. If so, you will need to reset it to be top left after rotation. Stevie |

Thanks. That's probably where the problem is. |
