Question - Code Is it possible to move vertex buffers in a room in GMS2?

[acidemic]

I am working on the 2D game where I have terrain being drawn using the vertex buffers. So far this was ok until I decided to introduce pieces of terrain with parallax movement. So now I want parallax affected terrain to move relatively to the main player's terrain. Programming parallax logic is not a problem, but i don't know how to draw the vertex buffers in other coordinates rather than where they were created. Is it possible to move vertex buffers around the room in GMS2. I don't need 3D.... just simple 2D.... even not that, just 1D.... ))) cause I need to move vertex buffer only against the X axis (basically change it's x coordinate).

Found only that GMS 1.x had function d3d_transform_set_translation() which is now obsolete in GMS2.

You can with matrices: https://forum.yoyogames.com/index.p...arted-with-3d-in-gms2-project-download.12145/

// matrix_build(x, y, z, xrotation, yrotation, zrotation, xscale, yscale, zscale);
var mat = matrix_build(room_width * 0.5, room_height * 0.5, 0, 0, 0, 45, 1, 1, 1);

// Apply matrix to drawing
matrix_set(matrix_world, mat);

// Submit your buffer here
vertex_submit(model, pr_trianglelist, -1);

// Reset matrix
matrix_set(matrix_world, matrix_build_identity());

Thank you! Will try this tomorrow.

FANTASTIC!!! It works flawlessly.
Worth noting that the code has to be used in Draw event.

I used "xmov" and "ymov" variables which would change only the x and y positions of the object on screen in order to create parallax movement effect. All other arguments are not used.

// matrix_build(x, y, z, xrotation, yrotation, zrotation, xscale, yscale, zscale);
var mat = matrix_build(xmov, ymov, 0, 0, 0, 0, 1, 1, 1);
matrix_set(matrix_world, mat);
gpu_set_texrepeat(1);
vertex_submit(ter_buffer, pr_trianglelist, ter_texture); // Drawing piece of textured terrain
gpu_set_texrepeat(0);
matrix_set(matrix_world, matrix_build_identity());
