如果你只是想单纯的用其他插件注册的变量,那么只需要将papi作为依赖即可，并在需要替换变量的地方写上PlaceholderAPI.setPlaceholders(替换内容, "待替换文本");
如果你想自己为自己插件的注册变量，那么你需要新建一个类，并且这个类要继承于PlaceholderExpansion，并重写以下方法
1. /**
2. * This method should always return true unless we
3. * have a dependency we need to make sure is on the server
4. * for our placeholders to work!
5. *
6. * @return always true since we do not have any dependencies.
7. */
8. @Override
9. public boolean canRegister(){
10. return true;
11. }
13. /**
14. * The name of the person who created this expansion should go here.
15. *
16. * @return The name of the author as a String.
17. */
18. @Override
19. public String getAuthor(){
20. return "someauthor";
21. }
23. /**
24. * The placeholder identifier should go here.
25. * This is what tells PlaceholderAPI to call our onRequest
26. * method to obtain a value if a placeholder starts with our
27. * identifier.
28. * This must be unique and can not contain % or _
29. *
30. * @return The identifier in {@code %<identifier>_<value>%} as String.
31. */
32. @Override
33. public String getIdentifier(){
34. return "example";
35. }
37. /**
38. * This is the version of this expansion.
39. * You don't have to use numbers, since it is set as a String.
40. *
41. * @return The version as a String.
42. */
43. @Override
44. public String getVersion(){
45. return "1.0.0";
46. }
48. /**
49. * This is the method called when a placeholder with our identifier
50. * is found and needs a value.
51. * We specify the value identifier in this method.
52. * Since version 2.9.1 can you use OfflinePlayers in your requests.
53. *
54. * @param player
55. * A {@link org.bukkit.OfflinePlayer OfflinePlayer}.
56. * @param identifier
57. * A String containing the identifier/value.
58. *
59. * @return Possibly-null String of the requested identifier.
60. */
61. @Override
62. public String onRequest(OfflinePlayer player, String identifier){
64. // %example_placeholder1%
65. if(identifier.equals("placeholder1")){
66. return "placeholder1 works";
67. }
69. // %example_placeholder2%
70. if(identifier.equals("placeholder2")){
71. return "placeholder2 works";
72. }
74. // We return null if an invalid placeholder (f.e. %example_placeholder3%)
75. // was provided
76. return null;
77. }
复制代码
最重要的一步是，不要忘记在你的主类启动时注册这个类， ,既在主类的onenbale()下写上或者其他能运行到的地方写上new 新建类().register()
