Unity Patterns | Customizing the Editor Part 2 – Menu Items & Undo. Quick Tips: Working with vertex colors | Unity Cookie. Working with vertex colors In this Design Unity Cookie Quick Tip, We will be discussing how we can paint vertex colors in Blender, Maya and 3Ds Max to use in Unity. Blender Starts at: 00:00, Max starts at 09:05, Maya starts at 07:10 Vertex painting is the art of assigning a color for each vertex to use in our shaders and they have a great number of uses, here are a few of my favorites: Tinting the color of a mesh.Baking occlusion to a mesh independent of a tile-able texture.Blending or swapping between textures within a shaderReducing the number of draw callsControlling non color variables in our shader such as specular power.Offsetting the uv coordinates within a texture atlas.
I have included my vertex color shaders in the resources for you to look through at your convenience. Referenced Tutorials in the Tip Got questions?

Unity – Assets In the previous article titled Introduction to Unity 3.5 I introduced the Unity interface and we created a simple project that shows a rotating cube. In this article, I want to introduce some basic Unity concepts such as the Asset pipeline and the GameObject-Component model and introduce a few of the Components that Unity provides. I will not go into too much detail about the different components in this article (I will dedicate a different article for each of the more complex components such as Terrain, Particle Effects, Physics, Audio, and Scripts).
Unity has probably the most comprehensive support for different asset types that you would want to use in your game. [Source] In most cases, you can simply drop the game asset in the Assets folder in your game project and Unity will automatically import it into the editor. Models Unity has native support for some model formats that do not require 3rd-party tools to be installed. Autodesk 3ds Max Autodesk 3ds Max Icon [Source] Modo. Rambling in 3 Dimensions.

If the force vector is parallel to a then the joint won't rotate. If it is parallel to b then you're just pulling along the bone, and the joint won't rotate. Armed with this reasoning, I decided that the torque on the joint was proportional to the sine of the angle between a and f and the sine of the angle between b and f. If the End Point is on the target, then you don't want the structure to move any more, but if the End Point is very far from the target, then you want the structure to move there quickly. One thing the previous two paragraphs do not tell you is which direction the joint needs to move. So, put these three things together, and you get: torque = Mag(f) * SinVect(a, f) * SinVect(b, f) * sign(CosVect(r, f)) * Sensitivity Where SinVect and CosVect return the sin and cos of the angle between two vectors respectively, Mag returns the length of a vector, and sign returns the sign of a number.
Joint axis through bone. GDC 2005 Proceeding: Handling Complexity in the Halo 2 AI. GDC 2005 Proceeding: Handling Complexity in the Halo 2 AI By Damian Isla Developers of game AI are always interested in cramming more complexity into the virtual brains they build. However complexity often has a price, or rather has many prices: poor run-time, poor scalability, a lack of directability and worst of all, a murky experience for the player in which the AIs seem to act "randomly" rather than "intentionally".
We will discuss the sources of complexity, the various ways in which complexity can manifest itself and also some of the architectural approaches we took in Halo 2 to mitigate these negative effects. This discussion will center on the problem of scalable decision-making, but will also touch on questions of memory, knowledge model, and control representations for the scripting and influencing of the AI by level designers. The Brute Force Approach to Common Sense We pay for complexity in a number of ways: Core Combat Cycle In the beginning, it's all very simple.
Behavior. AI in Swords & Soldiers (part 2) Last week I explained how we ended up with Halo 2-style behaviour trees in Swords & Soldiers, but I didn't really dive into how they actually work. So now let's have a closer look at how we worked with them. The small AI above gives a nice example of how our AIs work. The first thing to note here, is that behaviour trees are based on priorities. It is assumed that the AI will always want to perform the top-most action and will not look any further if that action can be executed.
In this case, the action at the top is shooting lightning at a Necromancer (useAbility). Necromancers create lots of skeletons, so killing them first is usually a good idea. To make this priority system work, the action at the top must have strong requirements, for otherwise the actions below it will never be executed. Since the AI must also mine gold, the action below that is building workers (createUnit). An interesting side-effect of these trees, is that they are also excellent for story scripting.

Отличительная черта языка — серьёзное отношение к типизации; во многом в этой связи язык назван в честь исследователя теории типов и изобретателя комбинаторной логики Хаскелла Карри. История[править | править исходный текст] В 1990 г. была предложена первая версия языка, Haskell 1.0.
В дальнейшем работа комитета продолжилась, и в 1999 г. был опубликован «The Haskell 98 Report[1]», который стал стабильным стандартом языка на много лет. Язык, однако, продолжал бурно развиваться, компилятор GHC был фактическим стандартом в отношении новых возможностей. Сейчас разработка новых версий языка идёт открыто, этот процесс получил название Haskell’[2] (Haskell Prime [ˈhæskəl praɪm], «Хаскелл-штрих»). Последняя версия языка — Haskell 2010 — была объявлена в конце 2009 г[3], но последней «значительной» версией (стандартом) остаётся Haskell 98.
Характеристики языка[править | править исходный текст] В качестве основных характеристик языка Haskell можно выделить следующие: Другие известные реализации:
Game Rendering » Instancing. Instancing is a new way to offload the CPU from some work when rendering many copies of the same geometry. It does it by reducing the overhead of drawing multiple copies of the same vertex buffer. In OpenGL it’s only fast to use instancing when the instanced mesh consists of very few triangles. Nvidias instancing demo, here with 136499 meshes rendered at once with 24 triangles per mesh. It runs at 20 fps stable on a GeForce 8800 GTS.
