Character pass through objects with mass

[macklebee]

As covered in the topic started by Angelwolf here: http://www.leadwerks.com/werkspace/topic/14318-my-monsters-can-run-through-walls/#entry98176

 

Characters can walk through objects that have mass no matter what the collision types are set. Attaching an example that shows the issue. The top box has mass and the lower box has no mass.

 

Example that shows the problem:

window = Window:Create("monster",0,0,800,600,17)

context = Context:Create(window)

world = World:Create()

camera = Camera:Create()

camera:Move(0,8,0)

camera:SetRotation(90,0,0)

camera:SetDebugPhysicsMode(true)

light = DirectionalLight:Create()

light:SetRotation(35,35,0)

 

ground = Model:Box(40,1,40)

ground:SetPosition(0,-0.5,0)

ground:SetColor(0,1,0)

shape = Shape:Box(0,0,0, 0,0,0, 40,1,40)

ground:SetShape(shape)

ground:SetNavigationMode(true)

 

box1 = Model:Box(1,1,5)

box1:SetPosition(0,.5,3)

shape = Shape:Box(0,0,0, 0,0,0, 1,1,5)

box1:SetShape(shape)

box1:SetMass(1000)

box1:SetCollisionType(Collision.Prop)

 

box2 = Model:Box(1,1,5)

box2:SetPosition(0,.5,-3)

shape = Shape:Box(0,0,0, 0,0,0, 1,1,5)

box2:SetShape(shape)

shape:Release()

box2:SetCollisionType(Collision.Prop)

 

world:BuildNavMesh()

 

monster = Model:Load("Models/characters/crawler/crawler.mdl")

monster:SetPosition(-4,0,0)

monster:SetCharacterControllerAngle(180)

monster:SetMass(1)

monster:SetPhysicsMode(Entity.CharacterPhysics)

monster:SetCollisionType(Collision.Character)

 

waypoint = {}

waypoint[1] = Pivot:Create()

waypoint[1]:SetPosition(4,.5,4)

waypoint[2] = Pivot:Create()

waypoint[2]:SetPosition(4,.5,-4)

waypoint[3] = Pivot:Create()

waypoint[3]:SetPosition(-4,.5,1)

wpt = 1

 

while window:KeyHit(Key.Escape)==false do

if window:Closed() then break end

 

if window:KeyHit(Key.Space) then wpt = wpt + 1 end

if wpt > 3 then wpt = 1 end

pos = waypoint[wpt]:GetPosition(true)

monster:GoToPoint(pos,2,3)

 

Time:Update()

world:Update()

world:Render()

context:SetBlendMode(Blend.Alpha)

context:DrawText("Press SPACE to move to next waypoint",2,2)

context:SetBlendMode(Blend.Solid)

context:Sync()

end

Thank you for the example. Testing it now.
