GetAABB
This function returns an entity's axis-aligned bounding box (AABB).
Syntax
- AABB GetAABB(number mode = GlobalAABB)
Parameters
- mode: this may be any of the following values:
- LocalAABB: the entity AABB in local space will be returned.
- GlobalAABB: the entity AABB in global space will be returned.
- RecursiveAABB: the recursive bounding box will be returned, encompassing the global bounding box of this entity, and the global bounding boxes of all its children.
Returns
Returns the entity's axis-aligned bounding box.
Example
--Create a window
window = Window:Create()
context = Context:Create(window)
world = World:Create()
local camera = Camera:Create()
camera:SetRotation(35,0,0)
camera:Move(0,0,-3)
local light = DirectionalLight:Create()
light:SetRotation(35,35,0)
--Create a model
local entity = Model:Box()
while true do
if window:Closed() or window:KeyHit(Key.Escape) then return false end
Time:Update()
world:Update()
world:Render()
entity:SetPosition(Math:Sin(Time:GetCurrent()/100.0),0,0)
context:SetBlendMode(Blend.Alpha)
local aabb = entity:GetAABB(Entity.GlobalAABB)
context:DrawText("AABB: "..aabb:ToString(),2,2)
context:Sync()
end
