I wonder if anyone could help me with this little problem. I am creating a grid based on some user defined dimentions. I have that working just fine. Now, I want the use to be able to enter points one the grid and have them show up... this is where I am getting hung up.
An example can be seen here in the design stages: http://worldclassdesigns.com/AI/setup.php
Example:
If the user has entered the following info:
Grid width (in number of blocks): 7 blocks
Grid height (in number of blocks): 3 blocks
it would print out like this.
* * * * * * * * *
* 0 0 0 0 0 0 0 *
* 0 0 0 0 0 0 0 *
* 0 0 0 0 0 0 0 *
* * * * * * * * *
This is a 7 by 3 grid with a surrounding box of *'s I will replace the 0's and #'s with pictures when this is completed.
now the user can enter as many places to put *'s as they want. So it might look like this:
* * * * * * * * *
* 0 0 0 0 0 0 0 *
* 0 0 0 * * 0 0 *
* 0 0 0 0 0 0 0 *
* * * * * * * * *
The user has entered 2 stars at the locations:
1st * i=4 and j=2
2nd* i=5 and j=2
This is where Im having the trouble. I need the code to print out the grid with the *'s in the selected areas.
Code:
I am currently working ont he bottom so yes, there are problems with it. Part one asks the user for the grid dimensions and number of obstacles. Part two asks for the locations of each obstacle. And I need part three to print the grid with the obstacles int eh correct place.
Please please please help,

Welcome to the A.I. Path Planner. <br>
Step 1 - Grid Setup<br>
Please fill out the form below. The grid name will
be used to pull up the project at a later date.<br> The grid
length and width is measured in number of blocks and will determine the area of
the <br> grid. The number of obstacles will be used
in a future step, but it refers to the number of <br>
blocks that will be taken up by obstacles.<br>
