After having a little look around about collisions. I can't seem to find what i'm doing wrong every time i touch the bottom of the tile it send's me through it and throws me out to the right of the tiles. I maybe going about this the wrong way if someone could help i'd be very grateful i'll copy all the relevant code down below.
void Game::update(float dt)
{
//check collision with world
vector<Tile>* world = level.getLevel();
for (int i = 0; i < (int)world->size(); i++)
{
if ((*world)[i].isAlive())
{
//if "alive" check collision
//world tile that are not alive don't do checks
if (checkCollision(&mario, &(*world)[i]))
{
mario.collisionResponse(&(*world)[i]);
}
}
}
bool Game::checkCollision(MySprite* sprite, MySprite* sprite2)
{
if (sprite->getAABB().left + sprite->getAABB().width <sprite2->getAABB().left)
return false;
if (sprite->getAABB().left > sprite2->getAABB().left + sprite2->getAABB().width)
return false;
if (sprite->getAABB().top + sprite->getAABB().height < sprite2->getAABB().top)
return false;
if (sprite->getAABB().top > sprite2->getAABB().top + sprite2->getAABB().height)
return false;
return true;
}
Mario Class
void Mario::collisionResponse(MySprite* sp)
{
//setPosition(getPosition().x, sp->getPosition().y - getSize().y);
//velocity.y = 0;
sf::Vector2f collide(getPosition().x - sp->getPosition().x, getPosition().y - sp->getPosition().y);
//check left side
if (abs(collide.x) > abs(collide.y))
{
if (collide.x < -5)
{
//right side
setPosition(sp->getPosition().x - getSize().x-1, getPosition().y);
velocity.x = 0;
}
if (collide.x > 5)
{
//left side
setPosition(sp->getPosition().x + sp->getSize().x + 1, getPosition().y);
velocity.x = 0;
}
}
else
{
if (collide.y < -5)
{
setPosition(getPosition().x, sp->getPosition().y - getSize().y);
velocity.y = 0;
}
else if (collide.y > 5)
{
setPosition(getPosition().x, sp->getPosition().y + getSize().y);
velocity.y = 0;
falling = false;
}
}
}
