Say I have 20 sprites on screen all created by the pan_create command and all using a pointer called PANEL* temp .They are created in a for loop until all are created.I know you can use event to trigger a function when the panel is clicked upon.My question is how do you pass the correct panel pointer to this
function in order to use the command ptr_remove(the panel )

Define a array with your Panelpointer:
PANEL* my_pan[20];

Then create it:
for(i=0;i<20;i++)
{
my_pan[i] = pan_create(content, layer);
}

Create all panels with "event=panel_click;" and this function elsewhere.
with renaming or inserting code as you wish.
