Rectangle to Circle Co.llision detection !

[raj_J2ME]

Hey Experts,
Please tell me how I can check the collision of moving image/circle and rectangle..
I mean there is a rectangle and 1 image/Circle is keep on moving then I have to check the collision detection..

Please make this possible as soon as possible,
Thanks,

Hi
Get the pixel information of both rectangle and moving image/circle. When moving object falls(or touches) into the pixels of rectangle area,then think the collision is happened.

Hi Raj,

for pixel-level collision detection you can use the Sprite collidesWith() methods: by setting its pixelLevel argument to true, the method will check only collision between opaque pixels.

If you're not using Sprite objects, only available method is to implement the collision detection by your own: checking a circle is not that difficult (you can use its radius and check for objects with a lower distance), but with more complex images/sprites it can easily become difficult.
