[C++] Wyciek Pamięci » 2024-09-24 18:09:35 Witam. W moim programie leci pamięć. Z tego co rozumiem to usuwanie starych prefabów powinno załatwić sprawę, ale jednak nie działa. Gdzie robię błąd ? for( auto & prefab: prefabsToPaint ) {
delete prefab;
}
GameObject * prefabToPaint; std::vector < GameObject * > prefabsToPaint; TerrainPrefab * ter = nullptr;
FloorPrefab * flo = nullptr;
void generateBrush() {
int baseX = int( worldMousePosition.x ) / int( tileSide ) * int( tileSide );
int baseY = int( worldMousePosition.y ) / int( tileSide ) * int( tileSide );
int brushHalfWdt = brush.size() / 2;
int brushHalfHgh = brush.size() / 2;
for( int y = 0; y < brush.size(); y++ ) {
for( int x = 0; x < brush[ y ].size(); x++ ) {
if( brush[ y ][ x ] == true ) {
int xx = baseX +( x - brushHalfWdt ) * tileSide;
int yy = baseY +( y - brushHalfHgh ) * tileSide;
if( prefabToPaint->type == gameObjectType::Terrain ) {
ter = new TerrainPrefab( prefabToPaint->name, dynamic_cast < TerrainPrefab * >( prefabToPaint )->ttype );
ter->position = sf::Vector2f( xx + 8, yy + 8 );
ter->collider->shape->setFillColor( sf::Color( 129, 48, 48, 128 ) );
ter->collider->shape->setPosition( sf::Vector2f( xx, yy ) );
prefabsToPaint.push_back( ter );
}
if( prefabToPaint->type == gameObjectType::Floor ) {
flo = new FloorPrefab( prefabToPaint->name, dynamic_cast < FloorPrefab * >( prefabToPaint )->ftype );
flo->position = sf::Vector2f( xx + 8, yy + 8 );
flo->collider->shape->setFillColor( sf::Color( 129, 48, 48, 128 ) );
flo->collider->shape->setPosition( sf::Vector2f( xx, yy ) );
prefabsToPaint.push_back( flo );
}
}
}
}
}
void painterUpdate() {
for( auto & prefab: prefabsToPaint ) {
delete prefab;
}
prefabsToPaint.clear();
if( GUIwasHover || GUIwasClicked ) {
return;
}
else if( tool == toolType::Cursor && selection_state == true ) {
mouseSelection();
}
else if( prefabToPaint != nullptr ) {
if( prefabToPaint->type == gameObjectType::Terrain || prefabToPaint->type == gameObjectType::Floor ) {
if( tool == toolType::Brush ) {
generateBrush();
}
}
}
I wszędzie zdefiniowałem destruktory: ~Collider() {
delete shape; }
GameObject( string name ) {
this->name = name;
position.x = 0;
position.y = 0;
collisioning = true;
mouseIsOver = false;
collider = new Collider( 16, 16, 16, true );
collider->shape = new sf::RectangleShape( sf::Vector2f( 16, 16 ) );
createTextname();
toDelete = false;
isVisible = false;
}
~GameObject() {
delete collider;
}

» 2024-09-24 19:20:59 Błąd miałem jednak w konstruktorze GameObjectu : GameObject( string name ) {
this->name = name;
position.x = 0;
position.y = 0;
collisioning = true;
mouseIsOver = false;
collider = new Collider( 16, 16, 16, true );
collider->shape = new sf::RectangleShape( sf::Vector2f( 16, 16 ) ); createTextname();
toDelete = false;
isVisible = false;
}
Poprawiłem kod i już nie ma wycieku pamięci: GameObject( string name ) {
this->name = name;
position.x = 0;
position.y = 0;
collisioning = true;
mouseIsOver = false;
collider = new Collider( 16, 16, 16, true );
dynamic_cast < sf::RectangleShape * >( collider->shape )->setOrigin( sf::Vector2f( 0, 0 ) );
dynamic_cast < sf::RectangleShape * >( collider->shape )->setSize( sf::Vector2f( 16, 16 ) );
dynamic_cast < sf::RectangleShape * >( collider->shape )->setOutlineThickness( 0 );
createTextname();
toDelete = false;
isVisible = false;
}
