Hello:<br>
I'm looking for some example code for a<br>
Point & Click Graphic adventure.<br>
What I need are routines to move a characture<br>
from it's current position to a new position<br>
given from a mouse click while going around<br>
obsticles or staying on a path.<br>
I can only find info for tile maps and that is<br>
not what I want.<br>
Any help would be appreciated.

* Which platform are you using?<br>
<br>
* Which programming language are you using?<br>
<br>
* Which compiler are you using?<br>
- If windows, are you using some API?<br>
- Are you using some library?<br>

In DOS the mouse interrupt is 33h which has a lot of functions. You have to initiate the mouse to be able to scan position and buttons. If you're using VESA for higher resolutions you'll probably need to set the mouse movement range (the area to which the mouse is restricted).<br>

/*<br>

i_mouse_init<br>
<br>
initiates the mouse using mouse interrupt 33h with function 00h. The AX register will resturn the "success" of the procedure, if AX is 0x0 (i.e. 0) the initialization failed, if AX is 0xffff (i.e. 65535) the initialization was a success.<br>

Sorry I was not clear,<br>
I am programming in c on Amiga & IBM compatible.<br>
I was'nt having trouble with the mouse but<br>
finding a path around obsticles. The information<br>
that I can find are tile based and I need something suitible for a game like King's Quest,<br>
Quest for Glory or Secret to Monky Island.<br>
These Games have a background to interact with<br>
and have irregular shaped obsticles and paths.<br>
I can use pseodo code or code in any language<br>
except assembly, I know nothing of assembly.<br>
Thanks for your responce.<br>
