ios - Basic Questions about Create Texture Atlas in Xcode -


i think might using texture atlases incorrectly, , wanted ask advice.

i found few sites online suggested create folder, let's ball.atlas, , in there, add animation frames (ball1, ball2, ball3).

then drag , drop ball.atlas actual xcode content tree, , reference atlas in code this:

 self.ballatlas = sktextureatlas(named: "ball")  self.ballimages.append(self.ballatlas.texturenamed("ball1"));  self.ballimages.append(self.ballatlas.texturenamed("ball2"));  self.ballimages.append(self.ballatlas.texturenamed("ball3"));  self.ballimages.append(self.ballatlas.texturenamed("ball4"));  self.ballimages.append(self.ballatlas.texturenamed("ball5"));

and can reference self.ballimages display animation, etc.

i saw guide, however, said go xcassets folder, , click '+', , hit 'new texture atlas', , creates folder. drag ball images in there.

there 1 fundamental difference here, however: in second approach, can specify @1x, @2x, @3x, whereas in first example (dragging folder) there no way specify.

what should doing? should not dragging anything, , instead put atlases inside xcassets collection?

thanks!

Image
i'm using qt framework build graphical user interface. use qgridlayout position qwidgets neatly. gui looks this: my application regularly adds new widgets gui @ runtime. these new widgets not added @ end of qlayout, somewhere in middle. the procedure bit cumbersome. applied on figure above, need take out widg_c , widg_d , ... qgridlayout. next, add widg_x and widg_y , , put other widgets again. how remove widgets qgridlayout: for in reversed(range(mygridlayout.count())): self.itemat(i).widget().setparent(none) ### as long you're dealing small amount of widgets, procedure not disaster. in application display lot of small widgets - perhaps 50 or more! application freezes second while procedure ongoing, annoying user. there way insert widgets somewhere in qlayout, without need take out other widgets? edit: apparently solution qvboxlayout simple. use function insertwidget(..) instead of addwidget(..) . docs can found link: http://doc.qt.io/qt-5/qboxlayou
