如何更改 tikz 树的字体大小

Question

是否有可能直接在以下树的行上更改文本的字体大小？我想缩小它，这样树就不会显得那么大。我希望有人能帮助我。谢谢！！

让节点中的 texz 字体大小变小很简单。我想到两种可能的解决方案：

• 定义节点样式，类似于edgenode/.style = {above,sloped,font=\small}然后相应地命名节点，例如node[edgenode] {....}

• 收集范围内的那些节点，在其中为范围内的每个节点进行定义。

第二种选择的完整代码是：

\node[dot,pin=135:{Spieler 2}] (n21) at (-4,-1) {};
