[pygame] Rendering Text By Line
It's pretty simple to split your string on carriage returns (and/or line feeds), create surfaces for each line of text, and blit those surfaces to the destination surface. I'm doing something like that. I haven't yet gotten word-wrapping to work, but the following out-of-context code does wrapping by line. It keeps track of text sent to a class, and a list of drawing surfaces each containing one character. When it redraws, it figures out where to place each letter so that they're in order without overflowing the allowed drawing area. def AddText(self,text,newline_at_end=True): In progress -- adding smooth word breaks. Adds to a list of drawing surfaces each containing one rendered letter. self.dirty = True text = str(text) ## Ensure format is correct. if newline_at_end: text += \n self.text += text ## Add the text as rendered surfaces, one character at a time. for letter in text: if letter == \n: self.text_letter_surfaces.append(None) else: rendered_letter = self.pen.Write(letter) self.text_letter_surfaces.append(rendered_letter) def RedrawText(self): Draws all current letter surfaces, automatically wrapping text so that text doesn't go outside the allowed area. self.dirty = False self.text_surface.fill((0,0,0,0)) letter_locations = [] LEFT_EDGE = 0 RIGHT_EDGE = self.cursor_rightmost_x NEAR_RIGHT_EDGE = RIGHT_EDGE - 100 cursor = [0,0] for letter in self.text_letter_surfaces: newline = False letter_locations.append((cursor[0],cursor[1])) if letter: ## Ie. if it's not None (a newline): ## Move the cursor for the next letter. cursor[0] += letter.get_width() if cursor[0] RIGHT_EDGE: cursor[0] = LEFT_EDGE newline = True else: ## This is a newline marker. cursor[0] = LEFT_EDGE newline = True if newline: cursor[1] += self.spacing_between_lines if cursor[1] + self.spacing_between_lines self.text_surface.get_height(): ## Move everything up. letter_locations = [[l[0],l[1]-self.spacing_between_lines] for l in letter_locations] ## Move the cursor back up, too. cursor[1] -= self.spacing_between_lines ## Now, actually put the letter surfaces onto my drawing surface. for n in range(len(self.text_letter_surfaces)): if self.text_letter_surfaces[n]: self.text_surface.blit(self.text_letter_surfaces[n],letter_locations[n]) ## Clean up: Delete characters that aren't visible, for next time. top = 0 - self.spacing_between_lines if letter_locations and letter_locations[0][1] = top: n = 0 last = len(letter_locations)-1 while letter_locations[n][1] = top and n last: n += 1 self.text_letter_surfaces = self.text_letter_surfaces[n:] self.text = self.text[n:]

My trouble with that engine was that I wasn't able to import new models into the thing, and that somebody mentioned having trouble getting the thing to run. There's also Panda3D, which is sort of a Python wrapper and actually includes Python in its download version. That one seems to have its own special EXE builder, so you can't just build your application your own way.

Perhaps. They're those things that look like cross-sections. See attached for what I made them look like.

[pygame] Finding the current view settings
Hi, I'd like to know how to get the current view settings. The idea here is to set the screen dimensions for fullscreen based on the display settings already in place before the game starts. Is there a way to do that? Thanks, Ian
