앵커 및 pgfkey 문제

~ 안에makeshape 패키지의 \pgfdeclareshape에 새 옵션을 올바르게 사용하는 방법@marmot가 해결한 문제를 포함하는 \ifx데 문제가 있었습니다 .\pgfdeclareshape

지금은 \pgfkeys. 그러나 이제 \anchor작업하는 동안 에 대한 옵션을 감지할 수 없습니다 \setpath.

코드는 다음과 같습니다.

나는 매우 혼란스러워요. 제발, 누군가 나를 도와줄 수 있나요? 나는 이것들을 모두 포기할 것이다.

답변2

해결책을 찾았습니다. 매우 쉬웠습니다. 나는 약간 어리둥절했지만 결국에는 명확하게 생각할 수 있었습니다.

나는 대체했다

\pgfkeys{
    /tikz/posicion manivela/.is choice,
    /tikz/posicion manivela/izquierda/.code={\def\pos@manivela{-1}},
    /tikz/posicion manivela/derecha/.code={\def\pos@manivela{1}}
}

~에 의해

\pgfkeys{
    /tikz/posicion manivela/.is choice,
    /tikz/posicion manivela/izquierda/.code={\xdef\pos@manivela{-1}},
    /tikz/posicion manivela/derecha/.code={\xdef\pos@manivela{1}}
}

이제 작동합니다.
