General discussions / How to create a build menu with the SFML view

« on: May 09, 2011, 06:38:18 pm »

First draw the scene and then the menu on top of it?

This!

I do it this way:

Code: [Select]

App->SetView(GameCam); (GameCam is a sf::view which can be moved by the user to look over the "battlefield")

App->Clear();  (Clear the window...)

Game->DrawAllTheThingsHappeningInTheGame();

App->SetView(App.GetDefaultView()); (The DefaultView does not move and so it allways "lays" over your GameCam and can draw all Hud elements)

Game->DrawTheHud();

App->Display();



Pseudocode btw.

General / Space Invaders - enemies. Best way to create them?

« on: November 17, 2010, 05:59:10 pm »

sf::Sprite enemy1(enemy);

and then...

list1.push_back (enemy);
list1.push_back (enemy);
list1.push_back (enemy);
list1.push_back (enemy);


Copy many of such lines and then just

App.Draw(enemy1);
App.Display();
or something else should be added? I think, there should, but I've no idea what.

I don't know, how far you are at programming...
but you should take a look at, classes, templates, loops etc.



At first, you have to define a Template for the List. That means, you have to define, what "type of element" it can hold.

For Example:

Code: [Select]


std::list<sf::Sprite> EnemyList; //Create a std::list, that can store sf::Sprites

sf::Sprite EnemySprite(enemyimage); //Create a Sprite

/* Now you have to fill the list, therefor you can use a for loop, instead of copying your code againd and again */


int enemy_rows = 3; //How many rows should there be?
int enemys_per_row = 15; //How many Enemys should be in one row?

for(int i = 0; i < enemy_rows; i++)
{

     for(int j = 0; j < enemys_per_row; j++)
     {
        EnemySprite.SetPosition(j*64, i*64); //For example, if you want 64 pixels space between every sprite
        EnemyList.push_back(EnemySprite);
     }
}



App.Clear();

for(std::list<sf::Sprite>::iterator it = EnemyList.begin(); it!=EnemyList.end(); it++)
{
  App.Draw(*it);
}

App.Display();







It's not perfect and totally correct, but it should get you in the right way.
If you don't understand, what I did there, you should first learn more C++
