I’ll post the problem here since it fits the latest beta version. My client simply closes on startup without any error message (Steam version). When I start it from Steam, the Project Manager opens. However, when I click on the project, it closes without any error message. If I load the last archived version, the client does open, but there’s an error with the MDL files, saying that MDL 303 is not supported. Everything was working fine in the version before the last beta update. I’m sorry I can’t provide more information since no error occurs.

i have fun with that .. now i have a flock of fishes with avoid collision and different movements. at the moment there is a flicker in pitch or in avoid collision . maybe i find a solution later or someone find a solution Flock = {} Flock.name = "Flock" function Flock:Start() world = self.entity:GetWorld() self.boxes = {} self.boxProperties = {} self.offset = self.entity:GetPosition() -- Position of the pivot used as offset -- Define Y-axis limits self.minY = self.offset.y -

ok thanks .. thats my solution not yet perfect but for now ok .. the boxes will be change with a fish model

new one.. but there is a problem with "otherbox" ^^ attempt to call a nil value (method "GetPosition") also math.atan2 dont works

I wanted to try to recreate the script in UltraEngine.

Hello, long time no see ^^ at the moment i have a littel time and i try to learn more with lua. I need help with my script. Maybe my thoughts completley wrong. I have a simple map with two boxes. One box is Main the second Box i made as a child each box has the script I'm trying to find out if the box is included in table. and how i can store it. maybe i am compleatly wrong.. maybe someone can help me FlockEntity = {name = "FlockEntity"} FlockEntity.maxforce = Vec3(0) --set to 20.005 then its hoovering (Mass = 1) FlockEntity.pointforce = Vec3(0) function FlockEntity:Start() self.tbl = {} self.entity:GetParent() self.entity:FindChild("Box*") print(index) print(self.tbl) print(name) end function FlockEntity:Update() ------ Hoover ---------------------- self.entity:AddForce(self.maxforce) ------------------------------------ -----------------Flock.lua------------------------------------------------------------------------ self.radius = 1 for i=1, #self.tbl do self.elem = self.tbl[i] if (self.elem ~= self.entity) then self.vNeighborDelta = self.elem:GetPosition() - self.entity:GetPosition() self.dist = self.vNeighborDelta:Length() if (self.dist < self.radius * 2) then self.vNeighborDelta:Normalize() self.entity:GetPhysicsMode() self.entity:AddForce(self.pointforce) end end end end RegisterComponent("Flock", FlockEntity) return FlockEntity

Maybe you can build this in blender and use the result as model?
