DrawPoly issues - Developers

Hey guys, I have been trying to draw a custom HP bar with the drawpoly tool. So I I have it done and stuff, this is what it looks like: [URL=http://s1187.photobucket.com/user/Fortune11709/media/polyhp_zpsf140b71c.jpg.html][IMG]http://i1187.photobucket.com/albums/z394/Fortune11709/polyhp_zpsf140b71c.jpg[/IMG][/URL] The only problem is it doesn't scale properly: [URL=http://s1187.photobucket.com/user/Fortune11709/media/polyhp2_zps71e6ea53.jpg.html][IMG]http://i1187.photobucket.com/albums/z394/Fortune11709/polyhp2_zps71e6ea53.jpg[/IMG][/URL] It goes all weird when set to 50 hp. Instead of halving it goes into quarters... Anything below 40-30 just makes it dissapear entirely. Code: [CODE]tbl = { {}, {}, {}, {} } tbl[1]["x"] = 150 tbl[1]["y"] = ScrH()/1.10 tbl[2]["x"] = 440*(health/100) tbl[2]["y"] = ScrH()/1.10 tbl[3]["x"] = 470*(health/100) tbl[3]["y"] = ScrH()/1.06 tbl[4]["x"] = 150 tbl[4]["y"] = ScrH()/1.06 surface.SetDrawColor(Color(255,25,25,255)) draw.NoTexture() surface.DrawPoly( tbl ) [/CODE] No idea what is wrong, that formula has worked on all the other health bars I have made.

That formula assumes it starts at 0, when points 1 and 4 say it starts at 150.

To something like this?: [CODE]tbl = { {}, {}, {}, {} } tbl[1]["x"] = 150 tbl[1]["y"] = ScrH()/1.10 -- I don't really know, can't test right now. tbl[2]["x"] = 440*(health/100) + 150 tbl[2]["y"] = ScrH()/1.10 -- I don't really know, can't test right now. tbl[3]["x"] = 470*(health/100) + 150 tbl[3]["y"] = ScrH()/1.06 tbl[4]["x"] = 150 tbl[4]["y"] = ScrH()/1.06[/CODE]

[QUOTE=Fortune11709;43483812]Ah, okay. So how should I go about fixing this issue? Should I change points 1 and 4 or 2 and 3. [/QUOTE] Well, that depends entirely on whether or not you want 150 pixels of space between your health bar and the left side of the screen (I assume you do.)

But why are you asking me for confirmation, instead of just trying it out?
