It's done! I used the "ANDROID_NDK"and it worked. Thank you very much!

No, I didn't. It happens when I click in Generate.

General / CMake error for SFML 2.3.2

« on: February 26, 2016, 07:53:14 pm »

Hello!
I'm trying to generate the makefile for SFML 2.3.2 with CMake, but I got this error:

CMake Error at CMakeLists.txt:6 (set):
  Syntax error in cmake code at

    C:/Users/MyUser/Downloads/SFML-2.3.2-sources/SFML-2.3.2/CMakeLists.txt:6

  when parsing string

    C:\Tools\Android\AndroidNDK\android-ndk-r9c

  Invalid escape sequence \T
Call Stack (most recent call first):
  CMakeLists.txt:24 (sfml_set_option)


What is wrong? And how do I fix this?
Thank you.

System / Re: Problem using threads

« on: June 20, 2013, 04:07:06 pm »

So at first I must create the block as pointers. Then I can use the delete. So what I did on the block class was just put in the destructor "delete this". In the main code I must declare the object as a pointer. But now I'm getting confused: how do I change the 3rd block of code I showed to you?

The line 144 is the sf::Thread blockThread(&Block::Collision<sf::CircleShape>ball, &blocks);

System / Problem using threads

« on: June 20, 2013, 03:30:56 am »

Hello.

I'm making a Breakout game and I'm getting some problems using sf::Threads. I'm trying to launch a thread per block to check if the ball collided with the block. I created in the class Blocks a method with a template.

I think that showing my code is the best way to understand what I'm saying.

The class:

Code: [Select]

class Block
{
public:
// Methods
Block(sf::Vector2f dimension, sf::Vector2f position, sf::Color color);
~Block();
template <class Obj>
void Collision(const Obj &object);

// Atributes
sf::RectangleShape blockShape;
sf::Vector2f blockPosition;
sf::SoundBuffer hitBuffer;
sf::Sound hitSound;
float blockLeft, blockRight, blockTop, blockBottom;
};

The method:

Code: [Select]

template <class Obj> void Block::Collision(const Obj &object)
{
// Collision variable
bool getCollision = false;

// Object borders
float objLeft   = object.getPosition().x - object.getRadius() / 2;
float objRight  = object.getPosition().x + object.getRadius() / 2;
float objTop    = object.getPosition().y - object.getRadius() / 2;
float objBottom = object.getPosition().y + object.getRadius() / 2;

if (objLeft <= blockRight)
getCollision = true;
else if (objRight >= blockLeft)
getCollision = true;
else if (objTop <= blockBottom)
getCollision = true;
else if (objBottom >= blockTop)
getCollision = true;

// Destroy the object in case of collision
if (getCollision)
this->~Block();
}

And the piece of code where I instantiate the blocks:

Code: [Select]

// "Draw" the blocks (vector)
std::vector<Block> blocks;
int row    = 4;
int colums = 15;

float spacement = 2.5f;
for (int i = 0; i < colums; i++)
{
Block block(sf::Vector2f(window.getSize().x / colums, 25), sf::Vector2f(i * window.getSize().x / colums + spacement, 100.f), sf::Color::Blue);
spacement += 2.5f;
blocks.push_back(block);

// Collision threads
sf::Thread blockThread(&Block::Collision<sf::CircleShape>ball, &blocks);
blockThread.launch();
}

The compiler says (line 114, where I create the sf::Thread):
"error: expected primary-expression before '<' token"
"error: expected primary-expression before '>' token"

Grateful for help.
