 This module will undergo changes.
```

## struct Ray*
```go
type Ray* = struct {
	pos: th.Vf2
	l: th.fu // length
	r: th.fu // rotation
}

```

Ray type.


## fn mk*
`fn mk*(pos: th.Vf2, l: th.fu, r: th.fu = 0.0): Ray {`

Makes a ray.


## fn getColl*
`fn (r: ^Ray) getColl*(s: []^ent.Ent, maxColls: th.uu): []ent.Coll {`

Same as ent.getcoll. Same changes will apply.


## fn getTilemapColl*
`fn (r: ^Ray) getTilemapColl*(t: tilemap.Tilemap, ic: ^th.Vf2): bool {`

Gets ray's collision to a tilemap.


## fn draw*
`fn (r: ^Ray) draw*(cam: rect.Rect, color: uint32, thickness: th.fu) {`
