Collision map behaviors

[pdiddles03]

I have a collision map with a single layer. But i want the character to behave differently when he collides with water than the rest of the tiles.  If i have the tile ID of the water, how can i program that?

There's the proper way of getting the tile ID etc. Haven't done it, but I searched for it when I had this issue.

Then there's the lazy way of making another layer specifically with the water tiles, that solves the different collision responses faster and easier.

I know how to get the different tile ID when colliding, but all that happens when colliding with tile is the velocity stops

There are two approaches:

1. Use Tilemap#setTileIndexCallback
2. Call arcade.collide
3. Return false from the callback that you set in (1)

or

1. Call arcade.overlap with a collisionCallback and processCallback
2. Filter the tiles with processCallback
3. Do something in the collisionCallback

You can see the first approach in examples/v2/tilemaps/tile-callbacks
