Surface makes sprite look worse

[Rivo]

Here is a pic of what my inventory looks like when drawn to the room without the surface:

Here's what it looks like when drawn to a surface:

Spoiler: Pic 2

The sprites are drawn separate. It can't be an issue with them overlapping since they are placed next to each other pixel perfect. So why is this happening? I know the difference is only small but I need it to be perfect. Can someone please help?

/// Draw inventory to surface

if !surface_exists(InvSurf) {InvSurf = surface_create(view_wview, view_hview);}
surface_set_target(InvSurf);

// draw base
draw_sprite(sBase, 0, view_xview+(view_wview)/2, view_yview+(view_hview)/4);

// draw descriptions
draw_sprite(sTLDescription, 0, ((view_xview+(view_wview)/2)-85)-55, view_yview+(view_hview)/4);
draw_sprite(sBLDescription, 0, ((view_xview+(view_wview)/2)-85)-55, (view_yview+(view_hview)/4)+64);

// draw scroll bar
draw_sprite(sScrollBar, 0, ((view_xview+(view_wview)/2)+85), (view_yview+(view_hview)/4)+28);

// draw exit button
draw_sprite(sExitButton, 0, ((view_xview+(view_wview)/2)+85), (view_yview+(view_hview)/4)-1);

surface_reset_target();

// draw surface
draw_surface(InvSurf, view_xview, view_yview);

Something that definetly strikes my brain is that you supply view coordinates when drawing to a surface.
You should also make sure to call

draw_clear_alpha(0, 0);

after you set the surface target and before you draw anything to the surface.

Okay then so, here's some new code I tried

if !surface_exists(InvSurf) {InvSurf = surface_create(room_width, room_height);}
surface_set_target(InvSurf);

draw_clear_alpha(0, 0);

// draw base
draw_sprite(sBase, 0, view_xview+(view_wview)/2, view_yview+(view_hview)/4);

// draw descriptions
draw_sprite(sTLDescription, 0, ((view_xview+(view_wview)/2)-85)-55, view_yview+(view_hview)/4);
draw_sprite(sBLDescription, 0, ((view_xview+(view_wview)/2)-85)-55, (view_yview+(view_hview)/4)+64);

// draw scroll bar
draw_sprite(sScrollBar, 0, ((view_xview+(view_wview)/2)+85), (view_yview+(view_hview)/4)+28);

// draw exit button
draw_sprite(sExitButton, 0, ((view_xview+(view_wview)/2)+85), (view_yview+(view_hview)/4)-1);

surface_reset_target();

// draw surface
draw_surface(InvSurf, 0, 0);

Still doesn't work :/

Try this

if !surface_exists(InvSurf) {InvSurf = surface_create(view_wview, view_hview);}
surface_set_target(InvSurf);

draw_clear_alpha(0, 0);

// draw base
draw_sprite(sBase, 0, view_wview / 2, view_hview / 4);

// draw descriptions
draw_sprite(sTLDescription, 0, (view_wview / 2 - 85) - 55, view_hview / 4);
draw_sprite(sBLDescription, 0, (view_wview / 2 - 85) - 55, view_hview / 4 + 64);

// draw scroll bar
draw_sprite(sScrollBar, 0, view_wview / 2 + 85, view_hview / 4 + 28);

// draw exit button
draw_sprite(sExitButton, 0, view_wview / 2 + 85, view_hview / 4 - 1);

surface_reset_target();

// draw surface
draw_surface(InvSurf, 0, 0);

And then draw the surface in the draw GUI event

I like to use surface_save() when debugging surfaces. It can help nail down whether the glitch is happening as you're drawing sprites to the surface, or when you're drawing the surface to the screen.

It's an odd glitch indeed. Try rounding all your coords just to see.

Yeah that didn't work either. I need it drawn on a normal draw event anyway.

I'll try rounding the coords then I guess, and see what happens...

Yeah you were right... Still kinda confusing and annoying to me :/ Ah well...
