Got some nice looking Fog of War system working with sprites (2D)! It might eventually work on mobiles too (although at lower resolution..) *Will be posting it to asset store hopefully within this month.. ** Update 2022: Now after those “few months”, project sources are […]

Started converting this 2D visibility/light script ( http://ncase.me/sight-and-light/ ) to unity, finally some progress! btw. lines are drawn using GLDebug from : http://www.unity3d-france.com/unity/phpBB3/viewtopic.php?f=24&t=5409 Unity forum thread: http://forum.unity3d.com/threads/2d-visibility-shadow-free.275698/ — TODO: – Quad segments are currently crossed.. – Fix mesh generation *Temporary fix:  insert extra boxes outside […]

Using Unity Indie, modified directional hard light shadows. Forum thread: – http://forum.unity3d.com/threads/free-directional-light-soft-shadow-unity-indie.257432/   How to: – Download builtin shader: http://unity3d.com/unity/download/archive – copied UnityCG, UnityShaderVariables, HLSLSupport, AutoLight to assets folder – renamed these as: UnityCG2, ​​UnityShaderVariables2, ​​HLSLSupport2​​ – created new shader file (that default diffuse) – […]

Another fake shadow test.. (similar to the old raycast version, but should work with Physics2D). *This is currently abandoned.. See also: http://unitycoder.com/blog/2014/10/12/2d-visibility-shadow-for-unity-indie/ Info: – Testing PseudoAngle to sort object positions Todo: – Take shadow caster PolygonCollider2D vertices, check which one are visible to play – […]

Interesting fake shadow effect for sprites, using modified sprite shader.. Features: – Works with animated sprites – Works without pro – Could be used as fake reflection also? – more info later.. Webplayer: http://unitycoder.com/upload/demos/FakeSpriteShadowShader/

Mooore fake shadows testing! (based on direct3D shaders) Info: – Works with unity indie/free! – Just a shader with sphere intersect function (so it basically only works with spheres..) – Point light & sphere positions are sent to the shader – Each sphere requires invidual […]

New realtime dynamic super version of the “Fake Realtime Shadows With Surface Shader“! Webplayer: http://unitycoder.com/upload/demos/FakeShadowShaderUnity/ — Image#2: Purpose was to make 2D shadow casting..but resolution is not good enough.. — Image#3: Or actually DX11 (#pragma target 5.0) gives extra ‘power’:

Converted this script to unity: FOV Using Recursive Shadowcasting, for a quick test.. Instructions: – Attach the script to a plane – use Unlit/Texture shader as material (then no need lights..) – Move main camera so that it sees the plane TODO: – Use this […]

Using the same code from previous 2D Raycasting Visibility Voxel Travelsal, but added dynamic grid array update (using screenshots..), so now the walls (obstacles) are updated realtime on the 2D grid. FEATURES: – Converted the whole thing to C# – Any object visible to camera can […]

Converted this shadow/visibility to unity:  Shadowcasting in c#  by Eric Lippert. Looks quite nice. Todo: – How to do ascii map? ( Gui.TextArea is not good..Or just use SetPixels.. Or use invidual planes with textures..) – Try with 3D objects/view? – Try with perlin generated […]
