Constructor
new TileCollisionLayer(pos, size, tileInfoopt, renderOrderopt, useWebGLopt)
Create a tile layer object
| Name | Type | Attributes | Default | Description |
|---|---|---|---|---|
pos | Vector2 | World space position | ||
size | Vector2 | World space size | ||
tileInfo | TileInfo | <optional> | Tile info for layer, tile() by default, none when no image is loaded | |
renderOrder | number | <optional> | 0 | Objects are sorted by renderOrder |
useWebGL | boolean | <optional> | true | Should this layer use WebGL for rendering |

Members
collisionData :Array.<number>
- Array.<number>
| Type | Description |
|---|---|
| Array.<number> | The tile collision grid |

isSolid
Properties| Type | Description |
|---|---|
| boolean | Solid layers block objects and particles, the solidOnly tests skip the others |
- Source
shadowSolidOnly
Properties| Type | Description |
|---|---|
| boolean | In the light system's shadow pass, cast only from the cells with collision, drawn as the layer shows them, so a floor in the same layer stays lit; false casts every tile |

Methods
clearCollisionData(layerPos)
Clear tile collision data for a given cell in the layer
| Name | Type | Description |
|---|---|---|
layerPos | Vector2 |
- Source
collisionRaycast(posStart, posEnd, callbackObjectopt, normalopt) → {Vector2|undefined}
Return the exact position of the boundary of first tile hit, undefined if nothing was hit. The point will be inside the colliding tile if it hits (may have a tiny shift)
| Name | Type | Attributes | Description |
|---|---|---|---|
posStart | Vector2 | ||
posEnd | Vector2 | ||
callbackObject | EngineObject | | <optional> | Callback, engine object, or undefined |
normal | Vector2 | <optional> | Optional normal of the surface hit |
- Source
- Type:
- Vector2 |
undefined
collisionTest(pos, sizeopt, callbackObjectopt) → {boolean}
Check if collision with another object should occur
| Name | Type | Attributes | Default | Description |
|---|---|---|---|---|
pos | Vector2 | |||
size | Vector2 | <optional> | vec2() | |
callbackObject | EngineObject | | <optional> | Callback, engine object, or undefined |

- Type:
- boolean
destroy(immediateopt)
Destroy this tile layer
| Name | Type | Attributes | Default | Description |
|---|---|---|---|---|
immediate | boolean | <optional> | false | Remove it now, as EngineObject.destroy does, children included |
- Source
getCollisionData(layerPos) → {number}
Get tile collision data for a given cell in the layer
| Name | Type | Description |
|---|---|---|
layerPos | Vector2 |
- Source
- Type:
- number
initCollision(size)
Clear and initialize tile collision, the size is the layer's own, the tile data and canvas keep it
| Name | Type | Description |
|---|---|---|
size | Vector2 | width and height of tile collision 2d grid |
- Source
renderShadow()
Draw this layer's shadow shape: the cells with collision in the part the shadow map covers, each row of them in one draw from that part of the layer's texture, so see through pixels in a tile cast nothing; every tile when shadowSolidOnly is off, or when the layer is turned or mirrored
- Source
setCollisionData(layerPos, dataopt)
Set tile collision data for a given cell in the layer
| Name | Type | Attributes | Default | Description |
|---|---|---|---|---|
layerPos | Vector2 | |||
data | number | <optional> | 1 |
