Hi Guys
Searching the forum and couldn't really find anything examplaining my problem
I want to be able to detect a specific "route" touch on the tablet.
EG. I'm busy developing a alphabet APP for the kids,
I want to show a image/sprite, eg: "A". now I want to detect the touch movement over the letter a, and if they go outside the borders?
will this somehow be possible?
Thanks
Danie

The GetPointer functions should be able to do the job. Search for GetPointer here

Hi
Thanks for the reply
Yes, I'm using getpointer, and getpointer pressed
I have 2 problems
1. How to make the "drawline" wider
2. How to detect if I hit the "border" of the letter
Thanks

You could use GetSpriteX/YFromWorld(). Then check if the values are outside the bounds of your sprite
You cannot change the thickness of DrawLine. You could probably use a combination of circles (at the points) and Boxes for the lines

HI
Thanks Blink0K

Got this kinda working with a Sprite.
Maybe not the correct way!
Will check now for detecting Spritecollisions using the GetSpriteX/YFromWorld()
