Brush:IntersectsBrush

This method can be used to test whether two brushes intersect.

Syntax

• boolean IntersectsBrush(Brush brush)

Returns

Returns true if the two brushes overlap, otherwise false is returned.

Example

Use the left and right key to move the blue brush. When the two objects intersect, it will turn red.

#include "UltraEngine.lua"

local window = Window("Ultra Engine", 0, 0, 1280, 720, displays[0], WINDOW_CENTER | WINDOW_TITLEBAR)
local framebuffer = Framebuffer(window)
local world = World()
local camera = Camera(world)
camera:SetClearColor(0.125)
camera:Turn(35, 0, 0)
camera:Move(0, 0, -6)
local light = BoxLight(world)
light:SetRange(-20, 20)
light:SetArea(20, 20)
light:SetRotation(35, 35, 0)
light:SetColor(3)
local brush = BoxBrush(world, 10, 2, 2)
local A = Brush(world)
local B = Brush(world)
local sliceplane = Plane(1, 1, -1, 0)
brush:Slice(sliceplane, A, B)
A:SetColor(0, 1, 0)

while window:Closed() == false and window:KeyDown(KEY_ESCAPE) == false do
    B:Move((window:KeyDown(KEY_RIGHT) - window:KeyDown(KEY_LEFT)) * 0.1, 0, 0)

    if A:IntersectsBrush(B) then
        B:SetColor(1, 0, 0)
    else
        B:SetColor(0, 0, 1)
    end

    world:Update()
    world:Render(framebuffer)
end

return 0
