oh your grid declaration, you can add a sample id.
then by checking if your mouse position intersects a certain cell of the grid, it will play that sample associated to it..
should be too hard

Cheesy,thanks for the reply, that's what i mean.My english is not too bad...

Ok, i have some question on this. I use array to store the grid top left corner position, then i am trying to detect if the mouse has enter the grid. Am i going to use some loop functions( such as for...)? Would that be slow? Or if there are some other types of method or algorithm that i can use?

I am new  to programming, so...Can someone give me some code sample on this? if there are any..

Wink

If your grid is regular (i.e. every cell is the same size, and there's no gaps between cells) then you can very easily get the cell number with the following code (I think):

Code:

int cx=mouseX/cellWidth;
int cy=mouseY/cellHeight;

//the mouse in in the cell 'cx' across, and 'cy' down.
