I’m also trying to achieve this. I am doing something similar to the original “Tony Hawk” combo display at the bottom of the screen (crazy move 1 + crazy move 2 + crazy move 3) kinda thing. Every time they do a move I’d like to add a " + " and “new move” to the list, and keep it centered at the bottom of the screen.
I can put a single text block into a wrap box and center it by setting it to align center + “fill empty space”, but the moment you add a second text block with the same settings, the first text block goes hard to the left while the new one is centered in the remaining space on that line.
I can achieve it with a horizontal box, but at some point I need it to spill over onto a new line like a wrapbox does. So the current planned workaround is to stick a horizontal box inside a wrap box, then when i’m adding a new text block I’ll check the length of the text block (in blueprint) against a set “max line length” (scaled by resolution) and if it exceeds it, add another horizontal box to the wrapbox and stick the whole text box in there. Though this does seem eerily familiar to the manual wrapping I was doing in canvas in UDK, urgh.
