click events?
Author
Hello i am new here and i have a question. I am busy creating a sea battle game but how can i make a onclick event on the boat so you can see it on the field?
if you need the code i'll post it for you!
We'll probably need to see some code to see where you are having a problem. What OS/API are you using?

i am using win32 here is the code(sorry for the comments its in Dutch):
you can make the boat's for you selfe because i cant upload them at this moment!

do i have to make a case for the left mouse button? en where do i have to place WM_LBUTTONDOWN?
you will probably end up with something like this:
The lParam 0x0000FFFF and (lParam 0xFFFF0000) >> 16 extract the mouse coords from the lParam var.
...EndPaint(hwnd, &ps);case WM_LBUTTONDOWN: HandleButtonClick(lParam 0x0000FFFF, (lParam 0xFFFF0000) >> 16); break;default: return DefWindowProc(hwnd, msg, wparam, lparam);}The lParam 0x0000FFFF and (lParam 0xFFFF0000) >> 16 extract the mouse coords from the lParam var.

i get 3 errors:

D:\Microsoft Visual Studio2\MyProjects\zeeslagv1\Main.cpp(598) : error C2059: syntax error : ')'
this is what i placed:

break;

I was using HandleButtonClick to stand in for whatever code you are going to use, just to show you where to put it and how to get the x, y coords. You have to write the function yourself [smile]
EDIT:
The point is that WM_LBUTTONDOWN, tells you when and where the left mouse button was clicked. It up to you then to respond approprietly. You can put whatever you like into HandleButtonClick, or whatever you want to call the function, the point is that it just holds the appropriete response to the message.
