Trouble Using dc.draw Functions

Former Member over 9 years ago

Hi Everyone!

I'm pretty new to Monkey C, and I've recently been having trouble with some stuff. For some reason, I cannot use any of the dc.draw commands.

(Meaning stuff like dc.drawText, dc.drawBitmap, dc.drawPrettyMuchAnything.)

I've followed tutorials and videos and checked out stuff on github, but for some reason whenever I type one of these functions in and run the program, it accepts the code, but does not draw what I have inputted. The parameters are all right and whatnot, but for some reason Eclipse skips right over it, not running any of the dc.draw functions I key in.

Has anyone else had this problem, and does anyone know a fix for it? I can't do much without all the draw functions.

Thanks!

If you are using View.onUpdate(dc), that will clear the screen and do the layout, so dc calls done before that won't be seen. do the dc calls after the View.onUpdate(dc).

If you are only doing dc calls…

If you are only doing dc calls (no layout), you don't need to call View.onUpdate(dc) at all.

Thanks!

Oh alright, I see. That did the trick!

I have one other question: I've loaded a bitmap as a background. When I draw text, it just appears as a white box on top of the picture. How could I fix that?

Thanks!

Use dc.setColor().

Lets say you want the text to be black with a transparent background.

dc.setColor(Gfx.COLOR_BLACK,Gfx.COLOR_TRANSPARENT);
