Is there a way get to work X_SPRITE on the gp2x? Models work fine, but X_SPRITE now drawing(
One alternative would be to create your own billboard, but you'd be create a model every loop.
Using the camera's vertical and horizontal angles with SIN and COS you can recreate a ortho sprite.
Not actually tested...
hang = //Camera horizontal angle
vang = //Camera vertical angle
width = 64
height = 64
hw = width/2
hh = height/2
x_s = COS(hang+90) * hw
x_e = COS(hang+90) * -hw
y_s = SIN(vang) * hh
y_e = SIN(vang) * -hh
z_s = COS(hang+180) * hw
z_e = COS(hang+180) * -hw
X_OBJSTART
X_OBJADDVERTEX x_s, y_s, z_e, 0, 0, rgb(255,255,255)
X_OBJADDVERTEX x_s, y_e, z_e, 0, 1, rgb(255,255,255)
X_OBJADDVERTEX x_e, y_s, z_s, 1, 0, rgb(255,255,255)
X_OBJADDVERTEX x_e, y_e, z_s, 1, 1, rgb(255,255,255)
X_OBJEND
May need some tweaking, but that's the basic idea. Although its unfortunate to hear the x_sprite doesn't work correctly, I've been using that in my recent project :(
