Hello all im having a bit of trouble here, so im trying to test myself by attempting to receate Zombies Ate My Neighbors (old snes game/2d top down shooter). The reason i choose this challenge was mainly because im not that creative when it comes to game design and things like that so instead im using premade sprites and level backgrounds. Now here is my issue, so with the level 1 background it comes all togther without boarders or colliders just one photo or sprite if thats the best way to put it. How should i go about making certin things interactable when its all just on sheet (the level has doors/pools/trees/grass bushes that act as boarders). I figured i could put colliders and somethings like the bushes and trees so the character doesnt walk right threw them but then that still leaves me with the doors that swing open and also the pool that you jump into…any ideas on how i can get this done or is it impossible??
p.s. i do have the sprites that have the door open as it shows on the top left corner… thank you to anyone that can help me out even in the slights
