I'd love the option to set a flag on an individual sprite to force it to always redraw. This would mirror the global
sprite.setAlwaysRedraw(flag) with a
My use case is a simple stopwatch sprite. It only needs to draw when the timer isn't paused. I could avoid the need for an update function to mark it dirty every frame and keep the logic entirely internal to the class if I could just toggle an always redraw flag for the sprite when pausing/unpausing the timer.
function Stopwatch:start() self.timer:start() self:setAlwaysRedraw(true) end function Stopwatch:pause() self.timer:pause() self:setAlwaysRedraw(false) self:markDirty() -- draw one last frame to make sure the final time is drawn end function Stopwatch:draw() font:drawText(string.format("%05.2f", self:elapsedTime() / 1000):gsub("%.", ":"), 0, 0) end
