| Summary | 0006320: Font drawing on develop | ||||
| Description | I'm trying to put some text on the screen on develop, but the text doesn't appear in the expected place. As far as I was able to understand from the engine code, the font handlers load default shader and should set right matrices for the shader. Still I got nothing. | ||||
| Steps To Reproduce | local fontfile = LUAUI_DIRNAME .. "fonts/" .. Spring.GetConfigString("bar_font", "Poppins-Regular.otf") local vsx,vsy = Spring.GetViewGeometry() local fontfileScale = (0.5 + (vsx*vsy / 5700000)) local fontfileSize = 25 local fontfileOutlineSize = 6 local fontfileOutlineStrength = 1.4 local font = gl.LoadFont(fontfile, fontfileSize*fontfileScale, fontfileOutlineSize*fontfileScale, fontfileOutlineStrength) function widget:DrawScreen() local px, py, sx, sy, cs = 500, 500, 800, 800, 8 local tcol = WhiteStr font:Begin() font:Print(tcol.."leftleft", px, py, 50, "or") font:End() end | ||||

1) update to 1965-g4c26c8e 2) px and py should not be given in pixels but in relative coords [0,1] |
|

Although the recent has made text to appear on the screen, it always appear in the left bottom part of the screen if px and py are within [0,1] range. If I go slightly over 1 or below 0 text just disappears, no actual movement of text is present. Also aren't normalized coords supposed to only be relevant with FONT_NORM option (which is not even exposed to Lua) font:Print(tcol.."leftleft", px, py, 0.05, "ocvB") P.S. I'm doing wrapper, so for me normalized or screen coordinates are just a small annoyance, but overall gamedevs will prefer to define their elements in pixels, as it's consistent with the rest of the emulated GL1.x functions. |

BTW, if called in DrawWorld font:Print() draws the text the same way as in DrawScreen* i.e. in screen space, rather than in the world space. If [0,1] coords in DrawScreen() are just small annoyance, then same [0,1] coords in DrawWorld() are totally user unfriendly (if it's not a bug). |

FONT_NORM normalizes the text *size*, not the coors. You indeed can't pass it to font:Print but that is easily fixed. "it always appear in the left bottom part of the screen if px and py are within [0,1] range" sounds like a wrong projection matrix, the default should always be equal to glOrtho(0, 1, 0, 1, -1, 1) with rescaled z if clipctrl is enabled. It seems LuaFonts is also missing WorldPrint, will be added later. |

>>>> the default should always be equal to glOrtho(0, 1, 0, 1, -1, 1) Am I supposed to construct Orthographic projection myself or did you mean it was an engine bug you were going to fix? |
