[RGSS]Issue with vertical text

[bigace]

Okay so I'm having an issue getting the text to be vertical. Here's the code:

#:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=
# ■ Bitmap 
#:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=
class Bitmap
	def gradient_fill_rect(*args)
		if args[0].is_a?(Rect)
			x, y, width, height = args[0].x, args[0].y, args[0].width, args[0].height
			color1 = args[1].dup
			color2 = args[2]
			vertical = args[3]
		else
			x, y, width, height = args[0..3]
			color1 = args[4].dup
			color2 = args[5]
			vertical = args[6]
		end
		dr = color2.red   - color1.red 
		dg = color2.green - color1.green
		db = color2.blue  - color1.blue
		da = color2.alpha - color1.alpha
		start_rgba = [color1.red, color1.green, color1.blue, color1.alpha]
		if vertical
			dr, dg, db, da = dr / height, dg / height, db / height, da / height
			(y...(y + height)).each do |i|
				fill_rect(x, i, width, 1, color1)
				start_rgba[0] = [start_rgba[0] + dr, 0].max
				start_rgba[1] = [start_rgba[1] + dg, 0].max
				start_rgba[2] = [start_rgba[2] + db, 0].max
				start_rgba[3] = [start_rgba[3] + da, 0].max
				color1.set(*start_rgba)
			end
		else
			dr, dg, db, da = dr / width, dg / width, db / width, da / width
			(x...(x + width)).each do |i|
				fill_rect(i, y, 1, height, color1)
				start_rgba[0] = [start_rgba[0] + dr, 0].max
				start_rgba[1] = [start_rgba[1] + dg, 0].max
				start_rgba[2] = [start_rgba[2] + db, 0].max
				start_rgba[3] = [start_rgba[3] + da, 0].max
				color1.set(*start_rgba)
			end
		end
	end
	def gradient_draw_text(*args)
		is_rect = args[0].is_a?(Rect)
		x        = is_rect ? args[0].x      : args[0]
		y        = is_rect ? args[0].y      : args[1]
		w        = is_rect ? args[0].width  : args[2]
		h        = is_rect ? args[0].height : args[3]
		text     = is_rect ? args[1].to_s   : args[4].to_s
		color1   = is_rect ? args[2]        : args[5]
		color2   = is_rect ? args[3]        : args[6]
		align    = is_rect ? args[4]        : args[7]
		vertical = is_rect ? args[5]        : args[8]
		align = 0 if !align
		vertical = false if !vertical
		text_bmp = Bitmap.new(w, h)
		text_bmp.font.name = font.name
		text_bmp.font.size = font.size
		text_bmp.font.bold = font.bold
		text_bmp.font.italic = font.italic
		text_bmp.font.outline = font.outline
		text_bmp.font.shadow = font.shadow
		text_bmp.font.out_color = font.out_color
		text_bmp.draw_text(0, 0, w, h, text, align)
		gradient_bmp = Bitmap.new(w, h)
		gradient_bmp.gradient_fill_rect(0, 0, w, h, color1, color2, vertical)
		w.times do |x2|
			h.times do |y2|
				alpha_txt = text_bmp.get_pixel(x2, y2).alpha
				if alpha_txt > 0
					c = gradient_bmp.get_pixel(x2, y2)
					c.alpha = alpha_txt
					text_bmp.set_pixel(x2, y2, c)
				end
			end
		end     
		draw_text(x, y, w, h, text.to_s, align)
		blt(x, y, text_bmp, Rect.new(0, 0, w, h))
	end  
end

So I was wondering if you guys could figure out where the issue is coming from.

What kind of vertical?
L
i
k
e

T
h
i
s

or rotated 90 degrees?
Either way, you have to change

        w.times do |x2|
            h.times do |y2|
                alpha_txt = text_bmp.get_pixel(x2, y2).alpha
                if alpha_txt > 0
                    c = gradient_bmp.get_pixel(x2, y2)
                    c.alpha = alpha_txt
                    text_bmp.set_pixel(x2, y2, c)
                end
            end
        end  

In its current state, it's only drawing horizontally. You have no check if it needs to be drawn horizontally or vertically.

The first vertical one, I'll take a look at that in a second thank you.

If this could be of any help to you, this draws text one char at a time vertically:

        chars = text.split('')
        y = 0
        while chars.size > 0
          text_bmp.draw_text(0, y, w, h, chars.shift, align)
          y += text_bmp.font.size
        end

Nope this happens:


I also tried this:

		if vertical
			y_off = 0
			text.each_char do |c|
				rect = text_size(c)
				rect.x = x
				rect.y = y + y_off
				draw_text(rect, c, align)
				y_off += rect.height 
			end  
		end

But this happenes:


Note: I've been trying to turn the word "Level"

Shouldn't you be drawing the vertical text to the text_bmp object? Because at the end of your method, you are calling a blt to copy the text_bmp object. Also, I have no idea why you have a draw_text immediately above that blt.
