Quick question, may be quick answer. My camera is showing me the outside part of the room, how do I set the camera to not view outside the room?

Try using clamp to limit the movement of the camera.
In the step event of your camera, add something like this:
In the step event of your camera, add something like this:
Code:
var xx = clamp(camera_get_view_x(view_camera[0]), 0, room_width - camera_get_view_width(view_camera[0]));
var yy = clamp(camera_get_view_y(view_camera[0]), 0, room_height - camera_get_view_height(view_camera[0]));
camera_set_view_pos(view_camera[0], xx, yy);

When I do that, it just only shows me the background color (outside the room?)

Yes, I'll post code as soon as I get back to my PC.

obCamera :: Create
obCamera :: Step
Code:
camera = camera_create();
var vm = matrix_build_lookat(x,y,-10,x,y,0,0,1,0);
var pm = matrix_build_projection_ortho(144,256,1,10000);
camera_set_view_mat(camera,vm);
camera_set_proj_mat(camera,pm);
view_camera[0] = camera;
if (room != rmTitleScreen) follow = obPlayer; else follow = obTitleScreenFollow;
xTo=x;
yTo=y;
Code:
if (room == rmTitleScreen) {
x+=(xTo-x)/6;
y+=(yTo-y)/6;
} else {
x+=(xTo-x)/8;
y+=(yTo-y)/8;
}
if (follow != noone) {
xTo = follow.x;
yTo = follow.y;
}
var vm = matrix_build_lookat(x,y,-10,x,y,0,0,1,0);
camera_set_view_mat(camera,vm);

I fixed it myself, was at first trying to do something with the view mat, but got a cool rotation 3d effect.
3d effect was:
var vm = matrix_build_lookat(x,y,-10, x = clamp(x, HALF_OF_VIEW_WIDTH, room_width-HALF_OF_VIEW_WIDTH),clamp(y, HALF_OF_VIEW_HEIGHT, room_height-HALF_OF_VIEW_HEIGHT),0,0,1,0);
Solution for me: added:
x = clamp(x, 72, room_width-72); // 72 and 128 are half my room width and height.
y= clamp(y,128, room_height-128);
after the if (follow) statement.
