ive tried using the built in shadow commands using the tutorial provided and it failed to produce any shadows on my model. i also tried using a shader i found. it produced some dark artifacts in random location but not even close to useable. is there a way i can perhaps draw a dark spot on my models texture based on a xyz source or something. im completely lost. proper lighting and shadowing kept me from ever producing a game and dark basic as well. does anyone know of a shader that exists on this free that works in agk?

Does your model have its own shader? If so, be sure to include these:



I think these needs to be on all models casting and receiving shadows. Don't forget the ground needs this, as well.

Have you set your object to cast and receive shadows, as well as the ground? I can't remember if those are both default to on.

You may also need to adjust the shadowrange via setshadowrange.

use this for the objects you want to cast shadow
SetObjectCastShadow ( objID, 1 )
use this command for objects you want to receive shadow
SetObjectReceiveShadow ( objID, 1 )

and if you are using this command set texStage to 0, not 1 as 1 will give it full brightness by default
SetObjectImage( objID, imageID, texStage )


here is an example of a block rotating around with a plane object for grass

i was able to get it to work seems it only works from the sun light source only able to be directed and not positioned. i need only a point light to cast shadows. sun shadows can be faked in a texture bake easy enough if they dont move but my game has a light that moves with the player underground. so sun shadows do very little good.

SetSunDirection( vx, vy, vz ) positions the sun


Green Gandalf has a thread about using many point lights using a shader

looks like his demo shows how ti use specular and normal mapping with point lights not shadows.

Thanks for the vote of confidence, but I don’t think it does. It’s probably just an unintentional illusion .

This could well be my next AppGameKit shader project - when I return from holiday .
