Var sprXOrig = sprite_get_xoffset(sprite) Var sprHeight = sprite_get_height(sprite) Var sprTex = sprite_get_texture(sprite, index) / draw_sprite_skew_ext(sprite_index, image_index, x, y, image_xscale, image_yscale, image_angle, image_blend, image_alpha, image_xskew, image_yskew) The following script can be used to extend Game Maker’s draw_sprite_ext() function. The triangles are then stretched and rotated to give you your scale and rotation. When you draw a sprite, you are creating two triangles to make a box.

The surface of the water is done by moving the vertices that lie on the surface of the water.Ī triangle strip is a combination of one or more triangles that is used as a surface to display textures. As an example of when we may need this, look back at my rope + water physics platformer engine. However, we have no way of warping the box into some other shape.

We also have variables that allow us to change the rotation and opacity of the box (image_angle and image_alpha). In Game Maker Studio we have variables that allow us to change the proportions of the box (image_xscale and image_yscale). Skewing is basically just the process of moving the vertices of a sprite so that the sprite is no longer viewed as a perfect box. In this article, I’d like to show off one way to achieve a particular procedural animation effect without the need for any sprite animations. I had a bunch of four-frame animations playing. Several people asked me if I made a ton of animations to make that happen or if I was doing some form of programming magic. In it, I displayed several GIFs where the grass and hanging vines would move a bit when the character interacted with them. Recently I posted an article called How To Make A Platformer FEEL Good.
