问题 The very useful feauture "Find usages" exists in Visual Studio and Resharper, but I can't find the same in Unity3D Editor. I see only "Select dependencies" in Unity3d, but I need the opposite one. Does it exist? 回答1: Unfortunately, Unity Editor allows you to find usages of an asset in Scene only. Moreover, what you get is selected list of assets using it, so after changing the mouse focus you'll lose your selection There's a solution on Asset Store that does: Find all usages of an asset, both

问题 How do I setup & use custom named colors in Interface Builder? 回答1: In Xcode9 you can add "New Color Set" to .xcassets files, where you can set rgba values or use IB's color picker. Then you can use that newly defined color from Interface Builder's color picker, it appears under the Named Colors section. Or you can use it from code like UIColor(named:"customColorName") . As for now, Xcode9 beta 1 does not support using string literal color names as UIColor (like it works with UIImages), but I

问题 So this is my first app and I am stuck and for almost a week I can't find a solution. I've created a lot of animations for different characters and found out that my game' memory usage is about 200 mb. Before I didn't worry about this because, as many beginners I thought that after I'll compress my png textures this size will decrease also. But that didn't happen. So I started to search what I can do about it and found out that changing the texture format from default RGBA8888 to RGBA4444 can
