Hey there. You’ll need to make sure you have a decent understanding of Unreal’s UMG system to be able to do too much. The HUD is all laid out using the UMG system and makes use of Overlays, Horizontal and Vertical boxes, etc. Unfortunately there’s no way to just “move” things around in UMG, you need to use the settings, paddings, borders, etc. to be able to achieve the look you want.
As for replacing the bar with a number - again, if you have an understanding of UMG this shouldn’t be too tricky. You can simple replace the health progress bar with a text box and use the same percentage to generate the text, rather than set the percent on the progress bar. The progress bar is expressed as a decimal-based percentage (0-1.0), so you would merely need to multiply by 100 to get a percent value (0-100).
I’d recommend maybe looking at a few tutorials on how to use the UMG system if you aren’t already familiar with how it all works. If you have too many issues let me know with a ticket via http://support.dapperraptor.xyz and I can show you some specific things but I’d start with learning some UMG tricks and tactics before trying to do too much to the widgets in the template
