I am planning to create an item inventory and going to use data structures for it.
Problem is that I don't know if there is any data structure that supports key/value pairs but with more... values?

I have my inventory items like this "item name | description | sprite | number in possession" so I need one key and 3 values,

e.g.

ds_something_add(myDS, "Potion", "Restores 50 HP", spPotion, 1);

They will also need to be sortable.

I made this script to check if two objects collide, thing is I want to use the bounding box instead of sprite width/height. I tried with bbox_right and bbox_bottom but couldn't get this done,

collidesWith(object1,object2);

{
	if (instance_exists(argument[0]) && instance_exists(argument[1]))
	{
    	return real(argument[0].x < argument[1].x + argument[1].sprite_width && 
    	argument[0].x + argument[0].sprite_width > argument[1].x && 
    	argument[0].y < argument[1].y + argument[1].sprite_height && 
    	argument[0].y + argument[0].sprite_height > argument[1].y);
   	//return 1 if true, 0 if false
	}
	else
	{
    	return -1; //return -1 if instance doesn't exist
	}
}

I am trying to make a two different animations for the jumping, and after, the falling state of a character. However the states got a bit messed up. So the full animation shows when the character jumps but not when he falls down.

Draw Event:

if (objPlayer.var_direction=='left')
{image_xscale = -1;}
else
{image_xscale = 1;}


if (objPlayer.var_action=='standing' && !(objPlayer.var_action=='falling') && !(objPlayer.var_action=='jumping'))
{sprite_index = global.spr_player_standing;image_speed = 0.2;}

/* action: Running */
if (objPlayer.var_action=='running' && !(objPlayer.var_action=='attacking') && !(objPlayer.var_horizontal_speed==0) && !(objPlayer.var_action=='pushing')
&& !(objPlayer.var_action=='falling')
&& !(objPlayer.var_action=='jumping')
)
{objPlayerSprites.sprite_index = global.spr_player_running; 

if(objPlayer.var_horizontal_speed < 0 && objPlayer.var_action=='running') 
	{image_speed = -objPlayer.var_horizontal_speed/10;} //this sets the image_speed to the right speed
if(objPlayer.var_horizontal_speed > 0 && objPlayer.var_action=='running') 
	{image_speed = objPlayer.var_horizontal_speed/10;}
}

/* action: Jumping */
if (objPlayer.var_action=='jumping' && !(objPlayer.var_action=='falling') && !(objPlayer.var_action=='attacking') && !(objPlayer.var_action=='running'))
{objPlayerSprites.sprite_index = global.spr_player_jumping;
if (image_index >11)
{image_index=10;}
}

/* action: Falling */
if (objPlayer.var_action=='falling' && !(objPlayer.var_action=='jumping') && !(objPlayer.var_action=='attacking') && !(objPlayer.var_action=='running'))
{objPlayerSprites.sprite_index = global.spr_player_falling;
if (image_index > 12)
{image_index=11;}else{image_speed=0.8;}
}

draw_sprite_ext(sprite_index,image_index,x,y,image_xscale,image_yscale,0,c_white,1);

My game is created in 1024 x 768, unfortunately my laptop screen is wide and when in fullscreen the graphics "break" if I choose to "keep aspect ratio".

Sprite left : fullscreen (sprite scales badly and pixels are "broken")
Sprite right: windowed (crisp)

Is there any way to achieve crisp graphics while mainting aspect ratio in fullscreen? Any way to do this by e.g. using surfaces to draw the game screen?

I have drawn this sprite of a plant, and I want to give it a windy motion like in the animation I did below,

I can do this by using frames, but I was wondering if there is another way to do this with code, like skewing the sprite somehow?
