:P Well:
1) How I can make a better structure?
2) Why the projectile_existence's value is not changed?
Thank you!

my compiler runtime checker - informs me that Line 47:
else if(r == py && c == px)
is a problem because variablepy and px are still uninitialised (when the program reaches that point).
So we can start by curing that problem.

That for loop starting on Line 28 - sure looks weird - but i suppose the consecutive if/else clauses make it a single statement loop.

Okay, I did fixed that py & px problem. Thanks!

And now, just to not flood the forum with many messages...

Why the goblin jumps several points (or simply disappear)? He should move just one point each time...
guestgulkan (2915)
I just realised, this is the same basic code as the thread about Setting the TextColor. I take it you've decided to give up on using a multi-colour display?
guestgulkan (2915)
Here is a Work In Progress, with color added (and some minor mods) with comments.
TODO:
1. Stop characters being able to move outside game grid
2. Possible timer - To allow automatic movement of the missile (is that what it is?) and the goblin.

Why this does not block the movement?

Well you will need either a default case that takes you back to the beginning, or a condition on the while loop, since if the user doesn't input anything, the case is basically skipped. Also...why do you have x += 0, y += 0, etc...those do nothing...

They where made just becuase that... to do nothing... I through in this way the smiley wouldn't move...

W00T!!! Did solved this! And was pretty simple... Just a empty else and deleting the two parenthesis, the ! mark, and invertin the signals (> would be <, etc). :DD

There is no reason to do that, it's basically wasting code...it's like doing stuff like this:

1
2
3
4
5
 
x = x;
;;;;;;;
!false;
if(true);
//etc...


They all have no meaning and are basically a waste...without them, the code will do the exact same thing.

Read my edit...

Now I did see something strange: The first hit, with the arrow (yep, is a arrow, not a missile), the goblin dosen't suffer nothing, and the secondtie he does gain 40 health... Then the third shot he dies... Why that happens??
