入力欄のこと

サンプル

cocos2d::ui::EditBox* _editPassword = ui::EditBox::create(Size(visibleSize.width/3, 30), "extensions/orange_edit.png");
_editPassword->setPosition(Vec2(origin.x+visibleSize.width/2, origin.y+visibleSize.height/2));
_editPassword->setFont("American Typewriter", 16);
_editPassword->setFontColor(Color3B::GREEN);
_editPassword->setPlaceHolder("Password:");
_editPassword->setMaxLength(6);
_editPassword->setInputFlag(ui::EditBox::InputFlag::PASSWORD);
_editPassword->setInputMode(ui::EditBox::InputMode::SINGLE_LINE);
_editPassword->setText("初期文字");
addChild(_editPassword);

文字取得

イベントを取得したいときのみEditBoxDelegateとsetDelegate(this)を追加する

Extensionは非推奨

cocos2d-x ui::EditBoxを使う

数字のみに限定する

setInputMode(EditBox::InputMode::NUMERIC);
