I need more that one more point of light for Dynamics Shader!

Hello everybody,

it’s my first post, I hope my english is comprehensible.

I recently subscribed to Dynamics Shader (porkfin software). It is really simple as it was described. There is only one problem.

I can only use just one light, if I try to activate more than one no error message appears, I see the newImageRects of all the lights but only the first one work.

Is it my mistake or is it a limitation of the plug-in?

I am writing an excerpt from the code.

 .... .... physics.start( ) physics.setGravity( 0, 0) DynamicShaderIsON = true -- just restarting background -------- LayoutScacchiera = "marmo" TipoScacchieraOld = 0 InizializzaScacchiera () local movement, lighting = shader.getMovement() debugLevel = shader.setDebugLevel(0) local N , angolo local objectPhysics = off -- set to false to turn off physics local objectMotion = off -- turns on slight motion for physics objects ----- Define the light source ----- angolo = 0 for N = 1, 3, 1 do angoloLuce[N] = angolo angolo = angolo + 120 light[N] = display.newImageRect( "immagini/light.png", 50, 50 ) light[N].x = centroLuce.x + math.sin(math.rad(angoloLuce[N])) \* raggioLuce light[N].y = centroLuce.y + math.cos(math.rad(angoloLuce[N])) \* raggioLuce local lightColor = {1, 1, 1} light[N]:setFillColor(lightColor) -- this is the default color ----- Add the light source to the Dynamic Shader ----- shader.addLight(light[N]) shader.setLightColor(lightColor) end -- for N = 1 , 3 ----------------------------------------------------------------------------------- local croce = display.newImageRect( "immagini/croceRock.png", 50, 50 ) croce.x = cx + 90 ; croce.y = cy - 90 croce.shaderInfo = {name = "croce", map1 = "immagini/croceRock.png", map2 = "immagini/croceRock\_n.png"} shader.addObject(croce) ----------------------------------------------------------------------------------- local cerchio = display.newImageRect( "immagini/cerchioRock.png", 50, 50 ) cerchio.x = cx - 105 ; cerchio.y = cy + 50 -- shaderInfo table required for the Dynamic Shader cerchio.shaderInfo = {name = "cerchio", map1 = "immagini/cerchioRock.png", map2 = "immagini/cerchioRock\_n.png"} -- add object to the Dynamic Shader shader.addObject(cerchio) ----------------------------------------------------------------------------------- ----- START THE DYNAMIC SHADER ----- ----------------------------------------------------------------------------------- shader.start() -- start shading luceDynamicShader = timer.performWithDelay(20, luceDynamicShader, -1 ) .... .... local function luceDynamicShader() local N =0 raggioLuce = 100 local cx, cy = display.contentCenterX, display.contentCenterY for N = 1 , 3 , 1 do angoloLuce[N] = angoloLuce[N] + 4 if angoloLuce[N] \> 360 then angoloLuce[N] = angoloLuce[N] - 360 end light[N].x = centroLuce.x + math.sin(math.rad(angoloLuce[N])) \* raggioLuce light[N].y = centroLuce.y + math.cos(math.rad(angoloLuce[N])) \* raggioLuce end -- for N = 1 , 3 end --local function timerLuceFaro()

As you can see there are three lights that rotate around a “centroLuce” center each at 120 ° from each other at a distance equal to “raggioLuce”.

In function luceDynamicShader ()  I simply spin the three lights.

Anyone have an idea?

Thannks in advance,

Alessio

Fixed: I has been contacted by email and they told me that, for the now, there is only one light source.

#3

Yes, someday after we finish transitioning graphics languages I’ll probably add another light source.

#4

Im a newb about this stuff but isnt the only way to do this by using the graphics effects which dont support more than one light source?

#5

Yes, especially if you are relying on composite paint like I do in the Dynamic Shader.  However, you can build a custom multi-light source shader at the graphics language level but I’m not an expert at that and I the effects I really wanted were available in composite paint. 

I’ve made some custom shaders now and will continue to explore that and I’ve also played around with faux multi-light effects using alpha overlays (circular with a highlighted area that can be rotated) and subtle flashes and light and glows in various colors to make is look like something is casting light.

Sporkfin make 3 light source and you’ll make me happy.

all that things will be avaible in the plug-in?

Probably not, for now just assume there will be one light source.  I’m continuing to support the Dynamic Shader but I’m uncertain when or in what ways I will upgrade it in the future.
