[How to calculate a mouseclick to select objects?]

ahh i just was focused on the window class sure camera class *facepalm*

 

 

thx rick!

[How to calculate a mouseclick to select objects?]

I have a camera with birds eye perspective and will now use my mouse to click on primitive objects to select them. I´m stuck a little bit how to get the objects behind my mousecursor. The Window Class only gives me functions like GetMousePosition. I have an idea to calculate a ray startpoint in relation to the xy position from my mousecursor in the window and send the ray with 90° into my world to see if there is a collision with an entity but that seems to be not that nice.

 

someone give me a hint?

[LUA for Leadwerks resources?]

I agree , basic Lua tutorials would help a lot to come more slowly to LE3 instead of being confused by too much stuff like tutorials dealing with camera, player, raycast all at same time.

Rick Wiki Snippets is ideal site to have such category we could name : "Lua in LE3 for beginners"

 

mhmm but where are tutorials for advanced people? I have the feeling that a lot of LE3 users buy leadwerks and think its a drag and drop clicktool where you can build a GTA 5 clone in 2 hours without any coding skills. I really would like to see some tutorials like introduce into shaders or some design patterns for game development. Sometimes I think new users are just lazy when I read some steamcommunity threads.

[Make a playground from primitives as "one big object"]

this behaviour is just confusing

[Release date for full?]

I would like to see something like a roadmap or a todo from josh that we can see the progress of Leadwerks 3

[LE 3.0 : terrain deleted still visible]

there are many bugs like this like the "cant unset material" or "create new/rename material"

 

 

hope they will be fixed soon.

[Make a playground from primitives as "one big object"]

create a pivot as parent. all boxes are childs. rotate the pivot

 

(cant test it right now but seems legit)

[The Poor Man's Cloud for Working on Your Game in Multiple Places]

raspi + mercury or git also nice

 

btw is there a learning effect

[Gameplay Tutorial Requests Here]

Light is on, light is off. I've messed around with some script, but I was trying to have a PushButton lua call a pivot which contained some custom code I wrote to turn the light off and it wasn't working... bah.

 

its supereasy just use PushButtonscript and create a new one with a flowgraph function like

 

Script:Toggle() --in

 

if self.entity:Hidden() then
self.entity:Show
else
self.entity:Hide()
end

 

and use this script with a light.

 

I really prefer more advanced tutorials

[Shooting]

should be possible to create some ballistcs like parabel and so an. I´m trying to do something like a bullet find its target always with a beziercurve. in 2d no problem to implement in 3d I need more time ;D

[Cut-tool]

why dont use something like blender or so to model a 3d object like a window and just import it?

no not the ball i will just Move the ground

Thx for Info

Josh should give us dev permissions also as indie Edition user

[What's the best way to light the inside of a light source?]

sooner or later you have to write your own shaders

[Cant find the right command to Update physics]

I rotated an entity (ground) with

 

function Script:UpdateWorld()
if App.window:KeyDown(Key.L) then
rotationNow = self.entity:GetRotation()
self.entity:SetRotation(rotationNow.x,rotationNow.y,rotationNow.z-1)

System:Print("X: " ..rotationNow.x .. " Y: " ..rotationNow.y .. " Z: " ..rotationNow.z)
end

if App.window:KeyDown(Key.J) then
rotationNow = self.entity:GetRotation()
self.entity:SetRotation(rotationNow.x,rotationNow.y,rotationNow.z+1)
System:Print("X: " ..rotationNow.x .. " Y: " ..rotationNow.y .. " Z: " ..rotationNow.z)
end

if App.window:KeyDown(Key.K) then
rotationNow = self.entity:GetRotation()
self.entity:SetRotation(rotationNow.x-1,rotationNow.y,rotationNow.z)
System:Print("X: " ..rotationNow.x .. " Y: " ..rotationNow.y .. " Z: " ..rotationNow.z)
end

if App.window:KeyDown(Key.I) then
rotationNow = self.entity:GetRotation()
self.entity:SetRotation(rotationNow.x+1,rotationNow.y,rotationNow.z)
System:Print("X: " ..rotationNow.x .. " Y: " ..rotationNow.y .. " Z: " ..rotationNow.z)
end

end

 

before rotation

after rotation

https://www.dropbox.com/s/t7p73t5x9tm969f/Screenshot%202014-01-18%2000.38.19.png

 

when I have probs (like the sphere) on the ground they ignore the rotation and stay in the air until I touch them (with FPSplayer)

 

 

I think I need some kind of UpdateShape() or UpdatePhysics()

 

 

someone could tell me the right command that my props act like they should ?

[How to develop with Leadwerks and more then one person?]

use git or subversion

 

 

svn may be easier for beginners

[What's the best way to light the inside of a light source?]

write shaders like:

dude. there are so many threads about that subject. your gpu doesnt support openGL 4....

[The Poor Man's Cloud for Working on Your Game in Multiple Places]

dropbox or create own server on owncloud

 

btw my dropbox is over 40 GB (student space race )

 

 

or best way

 

 

just work at one computer

[how i can i draw in a cubemap ?]

Whats the use of that? or why you will draw a big FRONT image into the skybox?

[Getting started with Terrain modeling]

i´m not interested into the LE 3 terrain editor (useless for me) I need lua/c++ functions from the LE3 API to load a .raw or export information about every pixel to create random worlds. I also have a script written with pure OpenGL but when the LE3 API have some functions to analyse .raw-maps it would be also nice

[Getting started with Terrain modeling]

I believe there are some free ones out there. All you need is a .raw file right?

 

jup.

 

how to evaluate the heightmaps? i dont see opportunely functions in the api

[How to make Triggers invisible?]

nope its not visible only in debug mode (press L) or if you turn triggerVisible to "true" @runtime

 

the script should not taken too seriously I only wanted to test if it is possible

[How to make Triggers invisible?]

I got it now. triggering just with shapes is possible

 

 

if someone is interested in:

 

just add this script to a pivot object and move it to the position where you want the trigger.

 

Size can be manipulated in the Script Tab

 

Press L to show triggers in debug mode

 

 

 

 

Script.Mapfile = "" --path Map
Script.triggerSize = Vec3(1,1,1) --vec3 TriggerSize
Script.triggerVisible = true --bool ShowTrigger
function Script:Start()
self.enabled=true
if self.triggerVisible then
--Create box
self.box = Model:Box(self.triggerSize.x, self.triggerSize.y, self.triggerSize.z)
self.box:SetPosition(self.entity:GetPosition().x, self.entity:GetPosition().y, self.entity:GetPosition().z)
self.box:SetColor(0,1,0)
end
--Create shape
self.entity:SetCollisionType(Collision.Trigger)
self.shape = Shape:Box(0,0,0, 0,0,0, self.triggerSize.x, self.triggerSize.y, self.triggerSize.z)
self.entity:SetShape(self.shape)
self.shape:Release()
end
function Script:Collision(entity, position, normal, speed)
if self.enabled then
self.component:CallOutputs("Collision")
System:Print("BAZINGA")
if(self.Mapfile) ~= "" then
--do a mapload
end

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

function Script:UpdateWorld()
if DEBUG then
if App.window:KeyHit(Key.L) then
if self.box == nil then
--Create box
self.box = Model:Box(self.triggerSize.x, self.triggerSize.y, self.triggerSize.z)
self.box:SetPosition(self.entity:GetPosition().x, self.entity:GetPosition().y, self.entity:GetPosition().z)
self.box:SetColor(0,1,0)
self.box:Hide()
end
if self.box:Hidden() then
System:Print("Trigger on")
self.box:Show()
else
System:Print("Trigger off")
self.box:Hide()
end
end
end
end

[How to make Triggers invisible?]

Could you explain what difference it would matter?

 

A material need resources to storage and there is a drawcall that "draw" the invisible material. I dont need both things in this case and it cost rendertime and storage in my RAM.

 

the minimal information I need is:

 

a nullpoint to find my trigger

and 6 faces (6*2 =12 triangles)

 

 

so I only have a nullpoint = 3 integers // x y z

 

and 12 triangles (12*3= 36 vertices) = 3*36 = 108 integers (or less because some vertices are the same)

 

(sure when I create objects there are more informations)

 

for a cuboid trigger

 

 

 

I would like to have something that isnt drawn in the world and just have shapes to detect collisions maybe a new entity?
