The behaviour of tiles is difficult to edit. LynnaLab can edit their basic solidity, but beyond that, their behaviour is hardcoded, or spread across dozens of different tables in the rom. This page will attempt to list those locations.
See the tile behaviour list if you just want to see the "end result".
There are 6 "collision modes". Each area is assigned a collision mode. Most of the tables related to tile behaviour are divided up for each collision mode, so certain tiles can behave differently depending on the context.
Each tile in an area has a byte associated with it, which is typically between
$00-$0f. This byte is editable in LynnaLab, but not in ZOLE.
$00 means no solidity, $0f means full solidity, and values in-between will set each quarter of the tile's solidity separately.
$10-$1f have special behaviour associated with them. See constants/specialCollisionValues.s.
Tables in the code
|tileUpdateRoomFlagsOnBreakTable||00:1184||List of tiles that have some effect on the room flags when broken (ie. remembering a bombable wall is opened).|
|hazardCollisionTable||00:2408||Lists which tiles count as holes, water, and lava. (This applies to most objects, but not to Link himself...)|
|warpTileTable||01:6238||List of tiles that cause warps to occur when touched.|
|invalidTimewarpTileList||01:6317||List of tiles which, despite being traversable normally, can't be timewarped onto. (Includes holes, whirlpools, and deep water (conditionally)).|
|enemyUnspawnableTilesTable||02:791f||Lists tiles that enemies can't spawn onto. (Solid tiles are automatically exempt, so are not listed here.)|
|facingDirAfterWarpTable||05:4a88||Sets Link's facing direction to particular values when a screen transition puts him on a particular tile (ie. stairs).|
|@doorTiles||05:4de7||Part of a bugged function which doesn't do anything, but which is supposed to center Link on door tiles after warping through time.|
|landableTileFromCliffExceptions||05:61bf||The tiles listed here (raisable floors) can be landed on when jumping down a cliff, even if they're solid.|
|tileTypesTable||05:7c6e||Specifies behaviours such as holes, water, lava, currents, conveyors, ice, etc. See data/tileTypeMappings.s.|
|cliffTilesTable||05:7d09||Lists the tile indices that count as cliffs that Link can jump off of, as well as the angle required for that to happen.|
|interactableTilesTable||06:43b2||Deals with things that should happen when Link is touching the tile; open a keydoor, push a block, spawn a ghini, open a chest, etc.|
|breakableTileCollisionTable||06:7818||List of tiles that can be broken, along with an index for "breakableTileModes".|
|breakableTileModes||06:78dd||Each index in "breakableTileCollisionTable" refers to an index here; this specifies in what ways it can be broken, what kind of animation to play, and more.
See also constants/breakableTileSources.s.
|itemPassableCliffTilesTable||07:4c50||List of cliff tiles that items can pass through from particular directions. Passing through these tiles will increase or decrease their "elevation level". The elevation level allows projectiles to pass both ways through cliff tiles, if they're high enough.|
|itemPassableTilesTable||07:4cc9||List of tiles that items can always pass through, regardless of elevation level.|
|itemConveyorTilesTable||07:4c3b||Lists conveyor tiles along with what directions they should push items in. (Only applies to item objects.)|
|seedDontBounceTilesTable||07:5134||List of tiles which seeds from the seed shooter don't bounce off of. Prevents ember seeds from bouncing off torches, bushes.|
|pushableTilePropertiesTable||08:452d||Defines what should go underneath a pushable block, and what the block should turn into when pushed (possibly a different tile that looks the same but is not pushable).
Each block here should have a corresponding entry in "interactableTilesTable".
Fully hardcoded behaviours
|Tile index||Tile name||Comments|
|$6e||MYSTICAL_TREE_TL||Game searches for this tile to place seed objects on|
|$d4-$d6||VINE_TOP/MIDDLE/BOTTOM||Animal companions can't pass through these, but Ricky can hop up and down them like cliffs.|
|$db||SWITCH_DIAMOND||Hardcoded to not break on using the switch hook|
|$fc||DEEP_WATER||Game checks this tile value to allow diving to underwater areas|
|Tile index||Tile name||Comments|
|$40-$47||Tiles $40-$43 correspond to staircase tiles $44-$47; they are automatically replaced when bit 7 of the room flags are set.|
