Possible to change color of render draw_text? (DEF-2697)(SOLVED)

Feature requests
#1

Is it possible to change the color of the text that the render script can draw? I know it’s just for debugging purposes, but that dark blue is really hard to read on any medium or dark background.

#2

Nope, it’s hardcoded. I guess we should make it configurable just as for draw_line.

Edit: Added a ticket for this (DEF-2697)

OK, thanks. Actually it’s kind of nice to not have to specify a color every time, but it would be nice if it was configurable. Ideally, both draw_line and draw_text would have a hardcoded default value and an optional color argument.

Exactly! That’s a nice backward compatible improvement.

I would absolutely love to see this in a future update. To be true, I really like to have even my debug screens look nice :wink:

Still needed! Just make it an extra options vec3 at the end for the color…

Yup, bumping this again. Trying to add some debugging stuff, but being stuck with this dark blue color really stinks.

We’ll discuss this in our next planning session on Monday.

We will add a new message and deprecate the old one (it will no longer be documented):

msg.post("@render:", "draw_debug_text", { text = "", position = vmath.vector3(), color = vmath.vector4() })

A workaround for those who find the debug texts too small (0.5x) on the retina display.

To scale debug texts you need DefOS and the following code in the render script:

local function get_display_info()
  local dummy_info = { mode = { scaling_factor = 1 } }

  local current_display_id = defos.get_current_display_id()
  if not current_display_id then
    return dummy_info
  end

  local current_display_info = defos.get_displays()[current_display_id]
  return current_display_info or dummy_info
end

function init(self)
  ...
  self.text_pred = render.predicate({ 'text' })
  self.display_info = get_display_info()
end

function update(self)
  ...
  local display_scale = self.display_info.mode.scaling_factor or 1
  local debug_text_projection = vmath.matrix4_orthographic(0, render.get_window_width() / display_scale, 0, render.get_window_height() / display_scale, -1, 1)
  render.set_projection(debug_text_projection)
  render.draw(self.text_pred)
end

function on_message(self, message_id, message)
  ...
  if message_id == hash('window_resized') then
    self.display_info = get_display_info()
  end
  ...
end

But also remember to scale the debug text’s position by display_info.mode.scaling_factor, otherwise it will be shifted on the retina display.
