I try to get the IndexSprite of the 2d list in my Level class to check if the player will be able to walk or not.
My problem is that i need to get the list with the index from my Level class, and i need to create a new object
ancienneListe but if i have a new one the index will all be set to 1 (i decied to have it to 1 by default if not set in my Leve class)
public MapRowColumn ancienneListe = new MapRowColumn; // new = index set to 1 and my player cant move
This is from my class Player:
public MapRowColumn ancienneListe;
public List<MapRowColumn.IndexLigne> nouvelleListe = new List<MapRowColumn.IndexLigne>();
if (Keyboard.GetState().IsKeyDown(Keys.Right) && old_right == false)
{
if (ancienneListe.Rows[joueur_position.X].Columns[joueur_position.Y].IndexSprite == 0)
{
direction = "droite";
joueur_position.X++;
old_right = true;
}
else if (ancienneListe.Rows[joueur_position.X].Columns[joueur_position.Y].IndexSprite == 1)
{
joueur_position.X = joueur_position.X + 0;
}
}
if (Keyboard.GetState().IsKeyUp(Keys.Right) && old_right == true)
old_right = false;
This is from my class Level:
public MapRowColumn map_row_column;
public Point joueur_pos = new Point(1, 2); // position du joueur
public Niveau1()
{
map_row_column = new MapRowColumn();
map_row_column.Rows[1].Columns[1].IndexSprite = 0;
map_row_column.Rows[1].Columns[2].IndexSprite = 0;
map_row_column.Rows[1].Columns[3].IndexSprite = 0;
map_row_column.Rows[1].Columns[4].IndexSprite = 0;
}
I hope this make sense and that you can help me, thank you
What I would do is pass the desired direction (ie: where we wanna move) and test accordingly with the key:
(If no need to move in diagonal)
for x: Hdir: 1 is to the right, -1 to the left, 0: no move
for y: Vdir: 1 to the bottom, -1 to the top, 0: no move
without the need of creation of an ancienneliste.
Something like:
if (Keyboard.GetState().IsKeyDown(Keys.Right))
{
Hdir = 1;
bool result = CanMove(joueur_position.X + Hdir, joueur_position.Y);
if(!result)
{
Hdir = 0;
}
UpdatePlayerPosition(Hdir, 0);
}
if (Keyboard.GetState().IsKeyDown(Keys.Up)) // for ex
{
Vdir = -1;
bool result = CanMove(joueur_position.X, joueur_position.Y + Vdir );
if(!result)
{
Vdir = 0;
}
UpdatePlayerPosition(0, Vdir);
}
...
bool CanMove(int x, int y)
{
//need to clamp values within the array !
if(x < 0)
return false;
if(y < 0)
return false;
if(x >= theworld.length)
return false;
if(x >= theworld.height)
return false;
bool value =theworld.Rows[x].Columns[y].IndexSprite == 0;
return value;
}
void UpdatePlayerPosition(int Hdir, int Vdir)
{
joueur_position.X += Hdir;
joueur_position.Y += Vdir;
}
More or less. This way you would only need to read directly the level, avoiding the use of 2 arrays.
The thing is that i have multiple class of Level (Niveau1 , Niveau2, etc…) all have different IndexSprite that i use to draw different texture in function of the index.
On my map i have my player and box that i can push around so i need those 2d arrays, the walls are not only in the border, there is some in the middle of my map.
By the way my project is to create a Sokoban, i have everything but the collision, my player and the boxes can go through the walls.
EDIT: i figure out how to get my IndexSprite but for some reason my player doesnt walk on all walkable texture (0 as IndexSprite)
I have a class like this for the 4 level i actually have
class Niveau2
{
public MapRowColumn map_row_column;
public List<Caisse> caisses;
public Point joueur_pos = new Point(5, 5); // position du joueur
public Niveau2()
{
map_row_column = new MapRowColumn(); // initialistion de la classe permettant de créer l'objet Rows (carte)
// Changer l'IndexSprite pour afficher une autre texture (0 = texture du vide, de base IndexSprite = 1 pour la texture du mur)
map_row_column.Rows[1].Columns[1].IndexSprite = 0;
map_row_column.Rows[1].Columns[2].IndexSprite = 0;
map_row_column.Rows[1].Columns[3].IndexSprite = 0;
map_row_column.Rows[1].Columns[4].IndexSprite = 0;
map_row_column.Rows[1].Columns[5].IndexSprite = 0;
map_row_column.Rows[1].Columns[6].IndexSprite = 2;
map_row_column.Rows[1].Columns[7].IndexSprite = 0;
map_row_column.Rows[2].Columns[1].IndexSprite = 0;
map_row_column.Rows[2].Columns[2].IndexSprite = 0;
map_row_column.Rows[2].Columns[3].IndexSprite = 0;
map_row_column.Rows[2].Columns[4].IndexSprite = 0;
map_row_column.Rows[2].Columns[5].IndexSprite = 0;
map_row_column.Rows[2].Columns[7].IndexSprite = 0;
caisses = new List<Caisse>(); // ajouter les caisses du niveau
caisses.Add(new Caisse(2, 2));
caisses.Add(new Caisse(3, 3));
caisses.Add(new Caisse(4, 4));
}
}
And i have a switch that create an object depending on the level i chose
public class Map
{
public Map(int _niveau) // permet faire les actions nécessaires en fonction du niveau choisi
{
switch(_niveau)
{
case 1:
Niveaux.Niveau1 niveau1 = new Niveaux.Niveau1();
map_row_column.Rows = niveau1.map_row_column.Rows;
map_caisses = niveau1.caisses;
map_joueur_pos = niveau1.joueur_pos;
break;
case 2:
Niveaux.Niveau2 niveau2 = new Niveaux.Niveau2();
map_row_column.Rows = niveau2.map_row_column.Rows;
map_caisses = niveau2.caisses;
map_joueur_pos = niveau2.joueur_pos;
break;
case 3:
Niveaux.Niveau3 niveau3 = new Niveaux.Niveau3();
map_row_column.Rows = niveau3.map_row_column.Rows;
map_caisses = niveau3.caisses;
map_joueur_pos = niveau3.joueur_pos;
break;
case 4:
Niveaux.Niveau4 niveau4 = new Niveaux.Niveau4();
map_row_column.Rows = niveau4.map_row_column.Rows;
map_caisses = niveau4.caisses;
map_joueur_pos = niveau4.joueur_pos;
break;
}
}
}
i know i can have an object Niveau1 , NiveauX … in one class but i’ll still need the switch to load one of these object once chosen in the menu or i’m completly wrong ?
PS: it’s the first game i ever make, i still have a lot to learn
A class is like ‘engine’ in a car. It is the thing that gives power to the car. But by instanciating it. It becomes an essence, diesel, gpl, electric engine.
You can have a class for the seats (that become an object covered of leather, velvet…)
So does the level class.
A class becomes an object when instanciated.
This was just to make things clear (i hope)
The level class should be generic to all levels to be loaded
Then in a global file, or one file per level, of type txt or xml or json etc, you store the levels definition:
Levelname:niveauX
Width:96
Height:64
Startposition:2,4
Caisses:5
Caisse1pos:3,5
Caisse1Tex:chemin/de/la/texture
Caisse2pos:3,6
Caisse2Tex:chemin…
