Title: Changing layers in top-down 2d
Post by: Seiryu33 on May 19, 2021, 04:01:31 AM

So this is one i've been trying to find information on. Specifically, for a top-down game, how would I program characters to jump from layer to layer? Like if the player character is on a ground layer and an enemy jumps down from above, how would I set that up?

Hi.
which part you have difficulties with?
Detecting player
Jump down?

to detect you can do for example a box cast(2D) (Ecosystem (https://hutonggames.fogbugz.com/default.asp?W1181))

To jump down you could disable the collider for a moment to pass thru the floor.

Like in Phantom Hourglass/Spirit Tracks where you can move from layer to layer: I.e, walking down staircases, being boosted up to another layer by wind gusts, etc. Like if I wanted to boost a character onto a layer above them.

Boost up you could use 'Add Force' or animate it with a Tween action

for stair cases use a flat surface as collider and rotate it to the degree your staircase is.

To kind of expand on the topic, how would I make characters fall down holes? For top-down games, you would have to set gravity to 0, but would still be the same basic issue of changing layers.

Hi.
Why would you need to set the gravity to 0?

you can rotate the camera to make it look topdown.

Also you can set gravity to a certain direction. (i believe somewhere in the project settings)

both can work
