记录每次研究源码的突破，今天已经将打字练习的功能完成了一个基本模型，先来看下运行效果。
godot源码增加打字练习的demo
这个里面需要研究以下c++的控件页面的开发和熟悉，毕竟好久没有使用c++了，先来看以下代码吧。
//第一排 显示文本 计时器 已完成个数 重新开始按钮HBoxContainer *version_info_first = memnew(HBoxContainer);// Add a dummy control node for spacing.Control *v_spacer_first = memnew(Control);version_info_first->add_child(v_spacer_first);hbc->add_child(version_info_first);VBoxContainer *hbc_first = memnew(VBoxContainer);hbc_first->set_h_size_flags(Control::SIZE_EXPAND_FILL);hbc_first->set_alignment(BoxContainer::ALIGNMENT_CENTER);hbc_first->add_theme_constant_override("separation", 30 * EDSCALE);vbc->add_child(hbc_first);typing_label_time = memnew(Label);typing_label_time->set_text("timer:"); version_info_first->add_child(typing_label_time);typing_label_count = memnew(Label);typing_label_count->set_text("complete"); version_info_first->add_child(typing_label_count);typing_restart_btn = memnew(Button);typing_restart_btn->set_text("restart");typing_restart_btn->connect("pressed", callable_mp(this, &EditorApathysTyping::_version_button_pressed));version_info_first->add_child(typing_restart_btn); 就这样就实现了文本框，输入框和按钮的实现，以及对应的事件，后面还有很多的功能，都需要慢慢的研究。
void EditorApathysTyping::_on_search_term_changed(const String &p_term) {ERR_PRINT(vformat("Blah: %s", p_term));String arr[17] = { "def", "div", "format", "enter", "tr", "table", "image", "td", "html", "float", "str", "var", "int", "else", "if", "for", "start" };int start = 0;int end = 16;int index = (rand() % (end - start)) + start;ERR_PRINT(vformat("Blah: %d", index));String should = typing_text_input_should->get_text();if (should == p_term) {typing_text_input_should->set_text(arr[index]);typing_text_input->set_text("");}if (should.count(should) < p_term.count(p_term)) {}下一步开始研究加工车间的面板，虽有难度，但也有挑战。加油吧
我们的目标你也来看一下吧
