If anyone knows of more efficient ways that’s nice too, do share them. To work around this problem you can tweak the “checking time” or invisible Sprite size.ī) create and delete buildings (especially if they have many objects) using External Layouts. Maybe it would be better for you to:Ī) make the invisible Sprite twice as big than the screen, and check it once every 0.2 seconds instead of every frame - however, the player might see an empty background for a little if the player is travelling very fast (falling in platformer games or using a car in top down games). However, that’s probably not very efficient since it’s checking for collision every single frame against many objects. s far as format, I always used PNGs for my pixel art and usually BMP for vector (just because its very similar to png and its Inkscapes standard export. Then turn the other building sprites not colliding with the invisible Sprite (that is, they are off screen) invisible.

if this invisible Sprite is colliding with the building sprites, make the building sprite visible. To do that in GDevelop (2d), you can use an invisible Sprite that is as big as the screen’s width and height (use ScreenWindowWidth()? I don’t remember the function name). In 3D, it works using something like render distance.

Line art is easy to create with the help of Bazier Tool from Inkscape, Bazier Curve. You’ll want to render a building only if it’s visible in the camera. A tutorial of transforming any photo to a line art vector using Inkscape.
