QUESTION
I'm developing a Game like paper.io in C++ with Win32 API. My Game data is stored in an array like:
1 = Player's Head
2 = Player's base
3 = Player's tail
- 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
- 0, 0, 3, 3, 3, 3, 3, 3, 3, 3, 3, 0, 0, 0, 3, 3, 3, 3, 0, 0, 0, 0,
- 0, 0, 3, 0, 0, 0, 0, 0, 0, 0, 3, 0, 0, 0, 3, 0, 0, 3, 0, 0, 0, 0,
- 0, 0, 3, 0, 0, 0, 0, 0, 0, 0, 3, 3, 3, 3, 3, 0, 0, 3, 0, 0, 0, 0,
- 0, 0, 3, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 3, 0, 0, 0, 0,
- 0, 0, 2, 2, 2, 2, 2, 2, 2, 2, 2, 0, 0, 0, 0, 0, 0, 3, 3, 3, 3, 0,
- 0, 0, 2, 2, 2, 2, 2, 2, 2, 2, 2, 0, 0, 0, 0, 0, 0, 0, 0, 0, 3, 0,
- 0, 0, 2, 2, 2, 2, 2, 2, 2, 2, 2, 1, 3, 3, 3, 3, 3, 3, 3, 3, 3, 0,
- 0, 0, 2, 2, 2, 2, 2, 2, 2, 2, 2, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
- 0, 0, 2, 2, 2, 2, 2, 2, 2, 2, 2, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
- 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
Now I want to fill the polygon (Player's tail) with the Number 2 (Player's base).
Scan Line Algorithm:
What works:
- If I scan the 5. line The first 3 trigger the algorithm and toggle the painting function. The next 3 toggles it again it stops the painting function again
Problems:
- If I scan the 2. line After Every 3 the painting function will be toggled and after the line, it will paint further, because it's an odd amount of numbers.
Solutions:
- Toggle on the transition from zero to non-zero (and non-zero to zero)
...Problems:
- I need to find the middle/spot to begin, that's in the polygon
ANSWER
Answered 2018-Jul-13 at 02:48There are a lot of special cases that make it tricky to determine which areas are inside the new base vs. outside, but this one is simple and reliable:
- Do a flood fill starting at the outer edges to find the area that is not in the base. This fill can cover any color except 1, 2, and 3
- Fill everything else with color 2 to make the new base.
QUESTION
(I do find a lot of similar questions, but so far non of these fits me...)
===========Updated error message, images, Command Line===========
I am trying to #include
(that's nearly all the code, the main function is almost empty yet) in visual studio, but it keeps reminding me cannot open source file "Python.h"
, if I run the program, it will raise an error:
fatal error C1083: Cannot open include file: 'Python.h': No such file or directory
. I added the include and library directories in project Property Pages
> VC++ Directories
, not working, tried to add the path to C/C++
> Additional Include Directories
, not working, and I tried to change it to release mode, still not working...
=================Update 2.0================
I add %(AdditionalIncludeDirectories);
to C/C++
> Additional Include Directories
but seems not work.
Then I did something really stupid: I copied the headers and .dll to the header include folder... Now it doesn't remind me can't find Python.h any longer, I can code:

Answered 2017-Jul-29 at 12:08In Visual Studio Community 2015 I changed the "Active solution configuration" in Build \ Configuration Manager from 'Debug' to 'Release. That solved this problem for me.
I got my following example code from: Tutorial Python embedded in C++
