[simple addForceAddPoint]

also the position of the pick appears to be pick.position with pick.position.x, pick.position.y, and pick.position.z

Doe you mean that the pick arguments are wrong? If so, what should they be?

[simple addForceAddPoint]

Change fw.main.camera to fw.Main.camera, when you have updated SDK from today.

Good to know, but that wasn't the problem I think.

[Model request]

Good work Omid, nice texturing as well.

[Mouse Picking Object]

sounds realy cool actualy. I just visited another topic, on which this idea really continues if you ask me: http://leadwerks.com/werkspace/index.php?/topic/559-model-request/

[Model request]

@Josh: that's so awesome and quite a coincedence.

 

I'm actually working on a script to get the doors to open dynamicly, just like in the Penumbra series. I was planning to do this as well for the drawers you are making now.

 

This script is for the entity or is it an adeption to the fpscontroller?

[How to make an Opacity Map function?]

For alpha mapping I use

texture0="abstract::lock.dds"
blend=2
depthmask=1
overlay=0
zsort=0
cullface=1
castshadows=1
specular=0.0
gloss=0.25
bumpscale=0.3
shader="abstract::mesh_diffuse.vert","abstract::mesh_diffuse_alphatest.frag"
shadowshader="abstract::mesh_shadow.vert"

[How to make an Opacity Map function?]

try to set the blend value higher. 2 or 4 might do the trick.

 

tex1 = the diffuse color

tex2 = the normal mapping (bump map)

tex3 = specular map (for glossines, making it more shiny)

[simple addForceAddPoint]

I'm trying to push an object forward. To do this I use the AddForceAddPoint command. I've searched the rest of the forum and I kind a get stuck with difining the force.

	pick=CameraPick(camera,Vec3(GraphicsWidth()/2,GraphicsHeight()/2,2.0),0,0)
if pick~=nil then
	if MouseDown(1)==1 then
		centerY=(GraphicsHeight()/2)
		if (centerY >= currentY) then 
			texty = 1
			campos = EntityPosition(fw.main.camera);
			force= Vec3(pick.x-campos.x,pick.y-campos.y,pick.z-campos.z)
			NormalizeVec3(force);
			force.x=10
			force.y=0
			force.z=0
			entity:AddForceAtPoint(force,pick.entity)

 

When I hold down the left mouse button and try to move a box, I recieve the error: index for obect is a valid filed or method.

Can someone tell me what I'm doing wrong here?

[Animation in Editor]

maybe this topic helps.

http://leadwerks.com/werkspace/index.php?/topic/329-lua-how-to-animate-models/

[Checking if mouseY is moving]

Now that I have a direction I can look into I can start puzzeling. I've created this sofar:

 

before main loop:

currentY = MouseY()

main loop:

centerY=(GraphicsHeight()/2)
		if (centerY >= currentY) then 
			texty = 1
		elseif (centerY <= currentY) then 
			texty = 2
		else
			texty = 0			end

 

after the update:

fw:Update()

--get the current Mouse Y position	
currentY = MouseY()

[Checking if mouseY is moving]

I'm looking for a way to see wether I'm moving my mouse in the Y direction (forward and backward).

if MouseDown(1)==1 then
		if MouseY = "Y moving forward" then
			do stuff
		if MouseY = "Y moving backwards" then
			do stuff
           end

 

Any suggestions?

[How to Start ?]

I assume you are going to buy a license of the program?

 

most of the tutorial on the leadwerks frontpage should help you get going for a few weeks. After that. try to make some content, (models, animations). If you are going for the sdk with LUA integration then I can suggest looking around in the example levels to see how lua files are set up. when you are familiar with programming you could try to start with very short game scripts or so. Also, make good use of the forum, don't hesitate to ask here and there.

[Undo Button]

grayed out? didn't know that. Still ctrl + Z also never worked.

[Undo Button]

make a feature request. This feature could be handy.

[Projection light]

File Name: Projection light

File Submitter: Aggror

File Submitted: 27 Dec 2009

File Updated: 27 Dec 2009

File Category: Lua Scripts

 

This spot light lets you choose a projector map via an extra menu. By default it display the leadwerks logo.

 

The material file contains this line:

[projector map]

The projector LUA is updated now, because of the latest 2.3 sync.

[Table index is nill]

it doesn't appear when saving. It happens when I press run. I normally press run to update the file so that every instance in the scene gets the new code. I could use the save button and nothing is wrong. I just wonderd what happens with the code when I run the script (F5). It does this every time I run it.

[Table index is nill]

I have copied the firepit code to my own firepit. The code is besides some default value exactly the same. However when you run the code you get the message : Table index is nill. Also the class.lua is opened with the line selected: classtable[modelreference]=class.

 

The object appears to be working normally but I wonder what the error message means.

[How to get good alpha blending?]

I think it looks really good!! Especially if you compare it with Dragon Age origines.

[resize the gizmo in the editor]

When you work on large scale scenes, you sometimes want to move an object. When this object is far away, it's realy hard to select an axis of the gizmo. Perhaps it's possible to scale the Gizmo with the + and - keys.

[light and switch messages]

I also tried to make my own messages: "LightOn" and "lightOf". This way I can call the entity.light instead of hiding the the lamp. It's the same as show and hide, but the difference is is that I can call light entities that are in a fixed position like the cagelight. But also here: I can only turn it off and not back on.

[SendMessage timing]

In the switch.lua is comment:

--Just set the key and everything will get updated automatically

 

 

So my guesses are that it updates instantly

[editor crashing]

it has nothing to do with what you typing. It happens a lot that that the engine crashes for no good reason. At least thats how it goes with me.

[light and switch messages]

The script I'm using is an entire copy of the original switch. It is exactly the same now, appart from the messages "activate" and " deactivate", which I replaced with Hide and Show. The base.lua message function looks like this.

if message=="hide" then
	entity.model:Hide()
	entity.hidden=1
elseif message=="show" then
	entity.model:Show()
	entity.hidden=0

 

I have added the entity.hidden=1 and entity.hidden=0 here.
