Just the answer I was hoping for! I will go learn more about shaders.

ty for the answer and have a good day!

General / Best way for day > night transition

« on: February 09, 2015, 09:05:44 pm »

hi i've made a small game with some simple textures as background

what would be the best way to make a like a day > night transition? aka go from bright to dark... sort of
I did some small research about shaders but didn't understand it very well

are there any easy ways to change brightness or something?
otherwise I'll just read up more on shaders I suppose

big thanks in advance! and apologise if these kind of threads are not "appreciated".....

General / sf::Text array

« on: July 25, 2014, 11:08:56 pm »

hello mates,

i'm developing a small 2d rpg but having difficulties when it comes to text and subtitles. first of all I wanted to do a text array for an npc, but it doesn't seem to respond to any variables other than the first one so to speak.
for example:

sf::Text npc_text[10]

npc_text[0].setFont(font);
npc_text[0].setString("greetings sire");

this works, but if I change to:

npc_text [1].setFont(font);
npc_text[1].setString("greetings sire");

it all of a sudden DOESN'T work, why?

how should I go about coding the texts and subtitles in a smooth way? i'm also not sure how I could set the fonts to all the texts in a simple way? other than typing:

npc_text[1].setFont(font);
npc_text[2].setFont(font);
npc_text[3].setFont(font);
npc_text[4].setFont(font);

etc etc.

i have attempted a for loop for this, but it has only resulted in crashes. mayhaps because of initializing too many fonts at once?

thank you mate

General / reason for the & sign

« on: July 04, 2014, 08:29:10 pm »

I created a function that looks like this:

void Draw(sf::RenderWindow &window);

... to draw a sprite.

but I don't understand why the & sign needs to be there...
what is it for? I can't seem to find out

Have you really not done this before? How to use functions and parameters is basic C++, maybe you should have a deeper look at a good book..

Yes... I suppose i've been too eager to just jump into game development without learning the c++ basics.
I'll go read a book

thanks anyway

So you mean I should have 5 different functions, one for each ball? I suppose it makes it easier to read but it's still just as much code.

It's not possible to just have this code:

Quote

if (!gamefinished && playerSprite.getPosition().x > obstacleSprite[0].getPosition().x - 30 &&
playerSprite.getPosition().y > obstacleSprite[0].getPosition().y - 30 &&
playerSprite.getPosition().x < obstacleSprite[0].getPosition().x + 20 &&
playerSprite.getPosition().y < obstacleSprite[0].getPosition().y + 30)
{
gamefinished = true;
musicsound.stop();
endgameText.setString(" YOU DIED\n\n\n\n\nYOU FINISHED GAME WITH: " + currentGold + " GOLD!");
}

work for all variables in the array instead of just (in this case, obstacleSprite[0])

General / Unnecessary blocks of code

« on: April 18, 2014, 02:02:22 pm »

Hello I'm after some tips regarding continous blocks of code related to the same things...

I've been thinking about some ways to handle it in a good way because the amount of code I've written seems a bit unnecessary and there must be some sort of way to make it simpler.

Let me give you an example:
I'm trying to create a game, and in it there are 5 different balls that you have to avoid. If you get hit by one of them you'll lose. So I typed this code to fix the collision:

Quote

         if (!gamefinished && playerSprite.getPosition().x > obstacleSprite[0].getPosition().x - 30 &&
         playerSprite.getPosition().y > obstacleSprite[0].getPosition().y - 30 &&
         playerSprite.getPosition().x < obstacleSprite[0].getPosition().x + 20 &&
         playerSprite.getPosition().y < obstacleSprite[0].getPosition().y + 30)
      {
         gamefinished = true;
         musicsound.stop();
         endgameText.setString(" YOU DIED\n\n\n\n\nYOU FINISHED GAME WITH: " + currentGold + " GOLD!");
      }

The problem is that I have to repeat this code for all 5 balls, and later on I'm thinking of adding more balls, so that would mean an immense amount of code. This is the case for a lot of things more than collision too, so there's so much code!!

How to make it smoother and easier to read?

thank you in advance!!

edit: to clarify, what I'm looking for is to how to make it happen for all variables in the array. I could look something like:
if (!gamefinished && playerSprite.getPosition().x > obstacleSprite[0, 1, 2, 3, 4, 5].getPosition().x - 30

General / Re: Trying to place collision in a class

« on: April 07, 2014, 10:10:26 pm »

No, what you quoted:

Quote

if(playerSprite.getPosition().x + 16 > screenDimensions.x / 2)
position.x = playerSprite.getPosition().x + 16;
else
position.x = screenDimensions.x / 2;

has nothing to do with player collision, it sets the screen to follow the player, what I meant was this class:

Quote

class PlayerCollision
{
public:
PlayerCollision(sf::Sprite playerSprite)
{
if (playerSprite.getPosition().x <= 0)
{
cout << "collision";
playerSprite.setPosition(0, playerSprite.getPosition().y);
}

if (playerSprite.getPosition().x >= 1536)
{
playerSprite.setPosition(1536, playerSprite.getPosition().y);
}

if (playerSprite.getPosition().y <= 32 && playerSprite.getPosition().x >= 833)
{
playerSprite.setPosition(playerSprite.getPosition().x, 32);
}
}
};

together with:

Quote

PlayerCollision pCol(playerSprite);

in the main loop.

Sorry for not being clear enough

Thanks!

General / Trying to place collision in a class

« on: April 07, 2014, 09:12:26 pm »

I've been busy trying to place my collision code (so you can't run outside the window) in a class, but seemingly fail to make it work.

Here's my source code:

Quote

#include <SFML/Graphics.hpp>
#include <iostream>

using namespace std;

class PlayerCollision
{
public:
PlayerCollision(sf::Sprite playerSprite)
{
if (playerSprite.getPosition().x <= 0)
{
cout << "collision";
playerSprite.setPosition(0, playerSprite.getPosition().y);
}

if (playerSprite.getPosition().x >= 1536)
{
playerSprite.setPosition(1536, playerSprite.getPosition().y);
}

if (playerSprite.getPosition().y <= 32 && playerSprite.getPosition().x >= 833)
{
playerSprite.setPosition(playerSprite.getPosition().x, 32);
}
}
};

int main()
{
enum Direction { Down, Left, Right, Up };

sf::Vector2i source(1, Down);

sf::Vector2i screenDimensions(800, 600);

float frameCounter = 0, switchFrame = 100, frameSpeed = 500;

sf::RenderWindow window;
window.create(sf::VideoMode(screenDimensions.x, screenDimensions.y), "SFML", sf::Style::Close);

window.setFramerateLimit(60);

sf::Texture pTexture;
sf::Sprite playerSprite;

sf::Texture bTexture;
sf::Sprite bImage;

sf::Clock clock;

bool updateFrame = true;
bool InMovement = false;

if(!pTexture.loadFromFile("Content/player.png"))
cout << "Error loading player image" << endl;

if(!bTexture.loadFromFile("Content/bg.png"))
cout << "Error loading background image" << endl;

playerSprite.setTexture(pTexture);
playerSprite.setPosition(70, 230);
bImage.setTexture(bTexture);

sf::View view;

view.reset(sf::FloatRect(0, 0, screenDimensions.x, screenDimensions.y));
view.setViewport(sf::FloatRect(0, 0, 1.0f, 1.0f));

sf::Vector2f position(screenDimensions.x / 2, screenDimensions.y / 2);

while(window.isOpen())
{
sf::Event Event;
while (window.pollEvent(Event))
{
switch(Event.type)
{
case sf::Event::Closed:
window.close();
break;
}
}

if(sf::Keyboard::isKeyPressed(sf::Keyboard::Up))
{
source.y = Up;
playerSprite.move(0, -3);
InMovement = true;
}
else if(sf::Keyboard::isKeyPressed(sf::Keyboard::Down))
{
source.y = Down;
playerSprite.move(0, 3);
InMovement = true;
}
else if(sf::Keyboard::isKeyPressed(sf::Keyboard::Right))
{
source.y = Right;
playerSprite.move(3, 0);
InMovement = true;

}
else if(sf::Keyboard::isKeyPressed(sf::Keyboard::Left))
{
source.y = Left;
playerSprite.move(-3, 0);
InMovement = true;
}
else
{
InMovement = false;
}

if(sf::Mouse::isButtonPressed(sf::Mouse::Left))
updateFrame = true;
else if(sf::Mouse::isButtonPressed(sf::Mouse::Right))
updateFrame = false;

if(updateFrame)
frameCounter += frameSpeed * clock.restart().asSeconds();
else
frameCounter = 0;

frameCounter = (updateFrame) ? frameCounter + frameSpeed * clock.restart().asSeconds() : 0;

if(InMovement)
{
if(frameCounter >= switchFrame)
{
frameCounter = 0;
source.x++;
if(source.x * 32 >= pTexture.getSize().x)
source.x = 0;
}
}

if(playerSprite.getPosition().x + 16 > screenDimensions.x / 2)
position.x = playerSprite.getPosition().x + 16;
else
position.x = screenDimensions.x / 2;

if(playerSprite.getPosition().y + 16 > screenDimensions.y / 2)
position.y = playerSprite.getPosition().y + 16;
else
position.y = screenDimensions.y / 2;

if(playerSprite.getPosition().x - 16 > screenDimensions.x / 2)
position.x = playerSprite.getPosition().x - 16;
else
position.x = screenDimensions.x / 2;

if(playerSprite.getPosition().y - 16 > screenDimensions.y / 2)
position.y = playerSprite.getPosition().y - 16;
else
position.y = screenDimensions.y / 2;

view.setCenter(position);

window.setView(view);

PlayerCollision pCol(playerSprite);

playerSprite.setTextureRect(sf::IntRect(source.x * 32, source.y * 32, 32, 32));
window.draw(bImage);
window.draw(playerSprite);
window.display();
}

return 0;

As you can see, the collision is in a class, and I'm not sure how it works, exactly.

And by the way,

Quote

if (playerSprite.getPosition().x <= 0)
{
cout << "collision";
playerSprite.setPosition(0, playerSprite.getPosition().y);
}

It actually outputs "collision" in the command prompt, but the collision just doesn't work.

Thanks in advance and have a good evening

I'm sorry if it's a stupid question, but what do you mean by "He still needs the release DLLs"?

OK, I compile the game in release mode and use the new .exe file it spits out, but where are the mentioned 'release DLLs' exactly?

I recognise a stupid question when there is one, but I don't understand

Right, I didn't even have debug / release in mind.

Oh and he downloaded it from me, there was a MSVCP110D.dll in my Visual Studio folder so I just sent it to him.

I'll try compiling in release and see what happens, thank you.
