Hi there,
I'm trying to make an image (png) go darker when in darker areas. (Image gets returned using Material)
Explanation using screens: ( sorry for large screenshots :) )

Now, as you can see in the screenshots above the plate stays as bright as before, and I would like to find a way to make it go darker aswell.
I tried several methods and none worked so far. (Code belown is original, without my failed attempts obviously)
My code:[lua]hook.Add("PostDrawTranslucentRenderables", "cl_drawplates", function( depth, sky )
if sky or depth then return end
for _,veh in pairs( ents.GetAll() ) do
if !IsValid( veh ) or
!veh:IsVehicle() or
veh:GetPos():Distance( LocalPlayer():GetShootPos() ) > DistanceFade then continue end
local vname = veh:GetNWString( "veh_name" )
local plates = GetVehiclePlates( vname )
if !plates then continue end
local pserial = veh:GetNWString( "plate_serial" )
if !pserial or string.len( pserial ) < 1 then continue end
render.SuppressEngineLighting( true )
for _,pinfo in pairs( plates ) do
cam.Start3D2D(
veh:LocalToWorld( pinfo.pos ),
veh:LocalToWorldAngles( pinfo.ang ),
pinfo.scale
)
surface.SetMaterial( plateMat )
surface.SetDrawColor( Color( 255, 255, 255, 255 ) )
surface.DrawTexturedRect( -pwidth / 2 - 6, -pheight / 2 - 6, pwidth + 12, pheight + 12 )
draw.SimpleText(
pserial, "PlateFontBig",
0, 0,
PlateTextColor,
TEXT_ALIGN_CENTER,
TEXT_ALIGN_CENTER
)
cam.End3D2D()
end
render.SuppressEngineLighting( false )
end
end)[/lua]
Thanks in advance.
Maybe remove the
[lua]render.SuppressEngineLighting( true )[/lua]
?

Not experienced with 3D2D neither shadowing, correct me if i am wrong
render.SuppressEngineLighting( true )
won't do anything.
You gotta draw it darker according to these functions:

Thanks, but how will that work exactly?
I'm not really good with anything clientside related such as derma, and these functions aswell..

I think they'll return the Color with the lightning to that area, now you just have to get the alpha and set the shadow of the plate with it(i think)
[editline]11th July 2014[/editline]
Something like this, i think:[lua] cam.Start3D2D(
veh:LocalToWorld( pinfo.pos ),
veh:LocalToWorldAngles( pinfo.ang ),
pinfo.scale
)
local asd = render.ComputeDynamicLighting( veh:GetPos(), veh:GetPos():Normalize() )
surface.SetMaterial( plateMat )
surface.SetDrawColor( Color( 255, 255, 255, asd.a ) )
surface.DrawTexturedRect( -pwidth / 2 - 6, -pheight / 2 - 6, pwidth + 12, pheight + 12 )
draw.SimpleText(
pserial, "PlateFontBig",
0, 0,
Color(PlateTextColor.r,PlateTextColor.g,PlateTextColor.b,asd.a)
TEXT_ALIGN_CENTER,
TEXT_ALIGN_CENTER
)
cam.End3D2D()
[/lua]

Let me test that out
EDIT: Nope,
[lua]bad argument #2 to 'ComputeDynamicLighting' (Vector expected, got no value)[/lua]
When I try this no error was given but problem remains the same though.
[lua]local asd = render.ComputeDynamicLighting( Vector(veh:GetPos()), Vector(veh:GetPos():Normalize()) )[/lua]
