GMS2 view_xview, view_yview

GameMaker Studio 2 has a list of obsolete function, including View Variables And Windows Functions.

From https://docs2.yoyogames.com/ , GMS2 introducing a camera function.

With the advent of the camera functions in GameMaker Studio 2, it means that a number of view variables are no longer required, specifically those referring to the view into the room rather than the view_port (which is still used). There are also a few functions for controlling how things are displayed that were available in legacy versions of GameMaker: Studio 1.4 which are also no longer appropriate. These variables and functions are listed below:

view_object     view_angle     view_xview     view_yview
view_hview     view_wview     view_hborder     view_vborder
view_hspeed     view_vspeed    
display_set_windows_vertex_buffer_method    
display_get_windows_vertex_buffer_method
display_set_windows_alternate_sync    
display_get_windows_alternate_sync    
room_set_view     

GMS1 center the view:

view_xview[0] = x - view_wview[0]/2;

view_yview[0] = y - view_hview[0]/2;

Alternative script for GMS2:

var view_xview = x - camera_get_view_width(view_camera[0]);
var view_yview = y - camera_get_view_height(view_camera[0]);
camera_set_view_pos(view_camera[0], view_xview/2, view_yview/2);

or obviously you can write it like this:

var view_wview = camera_get_view_width(view_camera[0]);

var view_hview = camera_get_view_height(view_camera[0]);

var view_xview_c = x - view_wview/2;

var view_yview_c = y - view_hview/2;
camera_set_view_pos(view_camera[0], view_xview_c, view_yview_c);

So we got a substitute for the code! We can continue to follow the GMS1 tutorial from youtube.

Well, not the greatest solution, but it works.

screenshake?
