c# - Assigning value of a Vector3 to another Vector3 -

-

कोड की निम्न पंक्ति में, _pro एक और वर्ग का उदाहरण है जिसमें रूपांतरण होता है नामित लक्ष्य और posi एक vector3 भी है और एक मान्य मान है। 

  _pro.Target.transform.position = नया वेक्टर 3 (posi.x, posi.y, posi.z);

मैं posi को Target.transform.position के मान को असाइन करना चाहता हूं लेकिन यह एक NullReferenceException ।

प्रत्येक भाग का निरीक्षण करने के बाद, _pro है null । यहां मैंने कैसे _PRO को इन्स्तांत करने की कोशिश की: 

  सार्वजनिक प्रक्षेपण _pro; GameObject go = GameObject.Find ("दुश्मन"); // जाना शून्य नहीं है _pro = go.GetComponent & lt; प्रक्षेप्य & gt; (); // _pro शून्य है

"दुश्मन" खेल जिस ऑब्जेक्ट में मिली थी, उसमें कोई प्रोजेक्सेल घटक नहीं है, इसलिए यही कारण है कि go.GetComponent & lt; प्रोजेक्लेइल & gt; () आपको null ।

आपको अपने कोड में प्रक्षेप्य को कहीं ज़ूम करना चाहिए। आप ऐसा कुछ कर सकते हैं: 

  go.AddComponent & lt; प्रक्षेप्य & gt; (); // जहां जाना है "दुश्मन" खेल ऑब्जेक्ट

या यह है: 

  var pro = CreateInstance & lt; प्रोजेक्ल & gt; (); Pro.transform.parent = go.transform.parent; // go "दुश्मन" गेम ऑब्जेक्ट है

java - Gradle dependencies: compile project by relative path -

Is it possible to specify a dependency on another gradeal project in the granular (in android studios) outside the current project limits? For example, with a relative path like this: dependence {collection project ('../../ stdlib / dagger'}} MyApp (path / user / foo / workspace / mypad) The app (Path / User / Foo / Workspace / MyPass / App) And I have an Android Library Project with 3 subdomules: stdlib (path is / user / foo / Utilities (Path / User / Foo / Workspace / Stadlib / Utilis) http (Path / User / Foo / Workspace / Stadlib / HT) / Li> What I have to do is compile the Dagger, Util, http module in the MyApp project. The Stidelib Library module under heavy development And MyApp will grow in the form of Growth, so I do not want to push them into a Mewen repository. I am a little change. is likely to add another Gredle projects in some way? I will push the study library into the Maven repository after the source is in search of a temp...
