Legacy GM Drawing Scale

[Imperial]

can you help me with drawing the sprites/texts, when I scale up or down the sprites/texts gets bigger

I want them to be Fixed please using the Draw Event, not Draw GUI

 

[FrostyCat]

If you aren't willing to do it properly and use Draw GUI, your only solution is to draw these sprites and strings at a scale inversely proportional to the zoom (e.g. half the size for a 2x zoom). Look up how to use functions such as draw_sprite_ext() and draw_text_transformed().

As frostryCat (GameGeisha..? Is that you?) said, i strongly recomend you use the draw_gui though.
Drawing in the normal draw event may seem like a good idea now, but you are probably shlpting yourself in the foot.
(There are ocasions where drawing in the GUI event is not an option, but given how you asked about a simple scaling question, i doubt the problem you are solving is such an ocasion).

Seriously though, @FrostyCat, its you, isnt it?

I Tried this but It's not correct

draw_sprite_ext(spr_gui_background,1,view_xview[view_current]+view_wview[view_current]-sprite_get_width(spr_gui_background),view_yview[view_current]+view_hview[view_current]-sprite_get_height(spr_gui_background),view_wview/1280,view_hview/720,0,-1,1);

How is it not correct? We need to know what you want to do with the sprite and its origin.

 

[GMWolf]

First transform coordinates from screen space to world space:

var wx = sx + view_xview; //sx is the x position on screen
var wy = sy + view_yview; //sy is y pos on screen.

Then scale:

var scale = view_wview/640;
//change 640 with another constant to change the scale.
//assumes a a constant aspect ratio.

Then draw like any other sprites using the variable calculated above.

[edit]
updated code below. I was tired when i wrote this

the sprite origin Is Vector2(0,0)

 

[Imperial]

xx = view_xview[view_current]+view_wview[view_current]-sprite_get_width(spr_gui_background);
yy = view_yview[view_current]+view_hview[view_current]-sprite_get_height(spr_gui_background);
wx = xx + view_xview;
wy = yy + view_yview;
draw_sprite_ext(spr_gui_background,1,wx,wy,view_wview/1280,view_hview/720,0,-1,1);

nothing happens

draw_sprite_ext(spr_gui_background,1,wx,wy,view_wview/1280,view_hview/720,0,-1,1);

Are you trying to center it or keep the original position?

Keeping It a the original position

What I think Fel666 was implying,

var scale = view_hview/720;

xx = view_wview[view_current ]- (sprite_get_width( spr_gui_background) )*scale;
yy = view_hview[view_current] - (sprite_get_height( spr_gui_background) )*scale;
wx = xx + view_xview;
wy = yy + view_yview;
draw_sprite_ext( spr_gui_background, 1, wx, wy, scale, scale, 0, -1, 1);

can you Fix the Pretenses

When I turn on my PC I'll work on some all purpose code that should work in any situation. But know that using the gui layer would be more correct, yeild better performance and reduce any artifacts due to scaling.

[edit]
here you go:
draw_sprite_fixed(sprite, index, xport, yport, scale):

///draw_sprite_fixed(sprite, index, xport, yport, scale);
var sprite = argument0;
var index = argument1;
var x_in_view = argument2 / view_wport[view_current];
var y_in_view = argument3 / view_wport[view_current]; //coordinates to draw in view (0 - 1)
var scale = argument4; //size of object

var x_in_room = (x_in_view * view_wview[view_current]) + view_xview[view_current];
var y_in_room = (y_in_view * view_hview[view_current]) + view_yview[view_current];

var xscale = scale * view_wview[view_current] / view_wport[view_current];
var yscale = scale * view_hview[view_current] / view_hport[view_current];
var rotation = -view_angle[view_current];

draw_sprite_ext(sprite, index, x_in_room, y_in_room, xscale, yscale, rotation, c_white, 1.0);
