Hello, I implemented Oliver's method of drawing Client Side Text into my mod, and it compiles without errors but does not draw the text. I discovered by using Msg that the code seems to locate the correct x,y position on the screen and attempts to draw the correct name to it, so the error is probably in this section here, my guess being the font:
vgui::surface()->DrawSetTextFont(m_hFont); vgui::surface()->DrawSetTextPos(x, y); vgui::surface()->DrawSetTextColor(Color(255, 255, 255, alpha)); vgui::surface()->DrawPrintText(sIDString, wcslen(sIDString)); Anyways, I am trying to draw the text above an entity that is stored as public in the player class, so that is what pJ is in the code, and yes pJ is fine as the player camera follows it, but the text isnt appearing over it. I call CJDrawer::DrawJumbles(this); in baseplayer_shared.cpp clientside, under calcview Header file here: http://pastebin.ca/443839 CPP file here: http://pastebin.ca/443849 And you can see I use GetVectorInScreenSpaceJumble, this is because I have the camera and text based on where the player's CJumble "pJ" is. Therefore: bool GetVectorInScreenSpaceJumble( Vector pos, int& iX, int& iY, Vector *vecOffset ) { Vector screen; // Apply the offset, if one was specified if ( vecOffset != NULL ) pos += *vecOffset; // Transform to screen space int iFacing = ScreenTransform( pos, screen ); iX = 0.5 * screen[0] * ScreenWidth(); iY = -0.5 * screen[1] * ScreenHeight(); iX += 0.5 * ScreenWidth(); iY += 0.5 * ScreenHeight(); //Cut out playing facing calculations since we calculate off the CJumble return true; }
