[CollisionTrigger.lua]

The program I am making is using the physics engine so making a program to follow the ball using SetPosition() and SetRotation() would be us less.

 

Why cant I like Macklebee is saying set the Collision respons becouse it seems to do notthing at the moment.

[CollisionTrigger.lua]

Yeah it will generate the Character Controller cylinder physics which is unwanted in many cases including this one most likely.

 

A work around is to move your entity and then make an invisible entity with character physics that will follow it (using SetPosition() and SetRotation()). Give your entity Debris collisiontype to avoid collisions with the invisible entity(with Character Controller physics) following it.

Might not be perfect but that is what I am doing until I can make custom collision responses and it works pretty good.

 

I have try that now Trigger will work it change its Physics Mode from Rigid Body to Character Controller.

But then it does not roll off course.

When you make object and make that a child of the ball all kinds of strange things happen. I get a giant ball in the scene and it will not detect any way.

 

So seams is no way to get a ball to be detected.

[CollisionTrigger.lua]

No did not change Physics Mode from Rigid Body to Character need it to be ball shaped.

This maybe a option I wonder what will happen when I shoot it in a hole though.

[CollisionTrigger.lua]

I have tried making the ball a character instead of a prop allready did not help.

Still would not detect it.

There must be something in Player prefab that makes it different becouse it is the only thing that is detected.

[CollisionTrigger.lua]

This is how the script in the ball looks it is linked in flowchart editor to out of CollisionTrigger.lua script.

 

Script.score = "0"
Script.hit_test1 = false
Script.hit_test2 = false

function Script:Ball_hit1()--in
self.hit_test1 = true
 if self.hit_test1 == true then
 self.score = "50"
 end
end

--[[function Script:Ball_hit2()--in
 self.hit_test2 = true
 end
]]--

function Script:PostRender(context)
context:SetBlendMode(Blend.Alpha)
	 if self.hit_test1 == true or self.hit_test2 == true then
local context=Context:GetCurrent()
 context:SetBlendMode(Blend.Alpha) --Set blend to alpha so only letters will show
		 context:DrawText("Score: ".. self.score .."",5,150) --Set text and position of text
 else
local context=Context:GetCurrent()
		 context:SetBlendMode(Blend.Alpha) --Set blend to alpha so only letters will show
		 context:DrawText("Score: ".. self.score .."",5,150) --Set text and position of text
 end
end

 

If I put in Player in the CollisionTrigger.lua script instead of ball it works fine.

Also try Name instead of name in CollisionTrigger.lua script but then script did not work any more when I tested it with Player.

[CollisionTrigger.lua]

This is how it is looking now:

 

 

--[[This script will make any entity act as a collision trigger.  It works best when you set the
entity's collision type to "Trigger".  This will continuously detect collisions without causing
any physical reaction.
]]--

function Script:Start()
   self.enabled=true
end

function Script:Collision(entity, position, normal, speed)
   if self.enabled and entity:GetKeyValue("Name") == "ball"
 	  then
 	  self.component:CallOutputs("Collision")
   end
end

function Script:Enable()--in
   if self.enabled==false then
    self.enabled=true
       self:CallOutputs("Enable")
   end
end

function Script:Disable()--in
   if self.enabled then
    self.enabled=false
    self:CallOutputs("Disable")
   end
end

 

 

It does not react on Player what is good but also does not react on ball (this is what the entity is called in the scene).

It seem it will not react on a prop.

Same happens in the Selective Collision Trigger 1.0 script.

[CollisionTrigger.lua]

I Found out my self that you have to drag the entity in to the box of the script to get it in.

 

It still does not trigger on the ball though.

[CollisionTrigger.lua]

I am trying to make a trigger box to detect a ball using CollisionTrigger.lua.

But it only detects the player.

 

How can I change this the ball is a prop and has a phy file.

 

Any help is welcome

 

 

I also tried the Selective Collision Trigger 1.0 but it does also not detect the ball

 

I also dont see how I can put a Entity in the box and even it I place it in the script it does not show up in the input box.

[Leadwerks and steam]

Distribution systems like steam are the future cutting out the middle man this is a good thing.

Becouse the middle man makes alot with out doing alot.

 

Also things like greenlight are great for inds.

[Particle Emitters Visible when Not in Line of Sight]

Maybe be you can make a option in the emmiter to say if you want it to be on all the time?

[Low Poly Modular pipes]

I like them save me a little time again

[Missing reflection shader]

What I did to have control over the shininess is make a range of shaders for 20% 30% 40% 50% 60% 70%

By changing the line "outcolor = mix(outcolor,texture(texture4,cubecoord),0.5); //mix diffuse with cubemap reflection 50%" to that values.

 

Works great

[Error loading texture]

See topic:

Material editor not working

[Material editor not working]

I tested on the 3.1 steam indie version to and same error.

 

What happens is that the last texture file you add the meta files are ruined the moment you press save.

 

You all so will see that the meta files are 1k after that. It only happens to the last file you put in the material.

 

I can send you the files if you need them?

 

I hope some one will look at this soon

[Best free tool to generate normal maps ?]

I really like Shadermap 2 it is not free but for $39.95 it is alot of program for your buck.

[Material editor not working]

I seam to have same problem in 3.1 beta steam ind version

 

This are errors I get:

Reinstalled leadwerks

 

And I have the same error now no matter what texture or shader I use when I try to make a material in the material editor:

 

Error: Texture file header not found.

Error: Failed to load texture "D:/leadwerks/RescueDrYoung/Materials/Metal/diamondsteel_spec.tex"

This looks like a bug in the material editor to me?

[Missing reflection shader]

@DanceTweety :

It's perhaps not the shader the problem.

Could you try to choose simple shader like normal map and see if the problem is occuring ?

(It could be some bug with Material editor)

 

Yes I will reinstall leadwerks just to besure

[Missing reflection shader]

Hi Shadmar,

 

I have edited the diffuse.shader to make it a reflective cubemap shader. But I have a problem every time I put a cubemap file in to the shader it seems like it is changed. It seem to work in material editor till I save it them the cubemap turns drank in the material editor and the cubemap file it self turns dark to.

 

This is how the Vertex part looks:

Maybe I did something wrong?

[Script to make boat sail]

I did that to. Was one of the first things I tried. But the motor simply takes of even though it is in boat in the scene tab.

 

That is why I tried the script with the hinge you see at top of this post.

[Script to make boat sail]

This is the example of how to do it but it is using a child box make in the script it self.

I want to us the child box as a motor so need a box where a can put the motor script in.

So how would I us a allready existing box in the Parenting script?

 

self.entity = Model:Box()

    local child = Model:Box(1,1,1)
    child:SetParent(self.entity)
    child:SetColor(1.0,0.0,0.0)
    child:SetPosition(2,-2,0)

    child = Model:Box(1,1,1)
    child:SetParent(self.entity)
    child:SetColor(0.0,1.0,0.0)
    child:SetPosition(-2,-2,0)

    return true

[Script to make boat sail]

Ok I will look how I have to put SetParent in my first script and hope it will work then.

[Script to make boat sail]

sorry don't know how newton engine works, I ment for you to make your own kind of "phisics engine" I also can't help much with scripts as I don't have tools.

All I have is tools for Unity 3D and knowledge from there.

 

I'm still waiting for 3.1 to be released, ...

 

but anyway let say you make boat parent of motor.

 

now motor is 45° turned

and boat rotates in direction that motor is for 0.45° each frame.

 

but because motor is child of boat the motor will stay at 45° and it will not turn.

 

but boat will turn.

 

 

well if you want to do with complete physics well good luck with that as people wanted to do it for normal walking and ended up using simulations - too much performance effective, ....

 

Ok I will try to find out how to make parent and child in leadwerks.

Thanks for the help so far.

[Script to make boat sail]

by proper parenting I mean making 2+ objects.

 

if you rotate the motor you don't want to rotate the boat.

 

BUT the boat should slowly want to rotate in direction of witch the motor is or is it inverse direction, not sure, ...

how fast it would turn you have to adjust that numbers in script.

 

I try to do that with a hinge in my first script but. I am not so good with the hinge command and dont see alot of examples.

Also did not get alot of feedback on that script it is at top of this post. I would like it if you could tell me how to couple 2 boxes one to be motor and one the boat then the newton engine could do its work and it would be simple.
