Title: [Example / Listing] Saving a Sprite as a File
Post by: Scooternew on April 16, 2006, 07:35:56 pm: I didn't see a tutorial section anywhere, so I'm posting here. This simply allows you to click a sprite and save it as a file. This isn't perfect - it doesn't include a menu (like in Windows), and it may capture gray area aroudn the sprite (or background) depending on how the sprite is shaped. Either way, this is how you do it.

Code: [Select]
temp_id = instance_position(mouse_x,mouse_y,all); if(temp_id != noone) { var tx, ty, tsw, tsh; tx = temp_id.x; ty = temp_id.y; tsw = sprite_get_width(temp_id.sprite_index); tsh = sprite_get_height(temp_id.sprite_index); screen_save_part("sprite.bmp",tx,ty,tsw,tsh); }
That can go in global left pressed.

There are some variables and/or functions to find the origin, that you'll have to subtract from the object position to get the left and top edges.

The only real times I could see this being used "usefully" would be in some kind of Game Maker paint program.
