I have to make a program that tracks the movement of the mouse cursor with a set of cross hairs.As the user moves the pointer, the crosshairs should move with it.

Okay...

Track the mouse with dbMouseX() and dbMouseY, and draw a circle or something every frame to those coordinates.

Here, this should work



I'm away from my computer right now, so I can't test it, If someone could see if it works, that would be great.

try moving dbCLS() before drawCrosshair(), otherwise everything drawn will just be cleared.

hey thank you much... that worked.. i also need help with a mouse rollover program if you can help me out.I have done it mostly..i just need to change some things in it.Actually i need to change the image with the detection of the cursor...if its on the image,it should change to second image and when the pointer goes away from the image i.e., the second one, the image should change back to first image.. i did it with fullclick function but that it is not right.

Although I will probably never consider myself the best source for good coding practices, I will probably just as much never mind giving what help I can. I have updated my profile so that my email is public. Whether you send me your queries, or post them here(if you put them here more than just me can help), I will give what advice I know.

As for the changing image, what you can do is check the mouse position(e.g. dbMouseX(), dbMouseY()) with the bounds of the image/sprite. meaning:
dbSpriteY() -Top
dbSpriteX() -Left
dbSpriteY()+dbSpriteHeight()-Bottom
dbSpriteX()+dbSpriteWidth() -Right

if it is in those, change the sprite from one to the other. and when it is out of those, change it back.

another method would be to make a single pixel sprite, and check to see if it is colliding with the image, if it is, make it the changed image, if it is not, then make it the original. I think this way would be easier than the first.
Hope that helps.

You can contact me at xadrieth@aol.com.

also, here's a bit more cleaned up version of the code above:


With the sprite rollover thingy, other then the one that Ultimate_H stated, could could use dbSpriteHit() or dbPoint().

If you use dbSpriteHit(), you would though need to to load up an image file for the cursor, but if you can do some fancy artwork, you could make a nice looking cursor
