What is the need for normalizing a vector? - Stack Overflow
2012年4月4日 · The Cartesian coordinate system that we use is an orthonormal basis (consists of vectors of length 1 that are orthogonal to each other, basis means that any vector can be represented by a unique combination of these vectors), when you want to rotate your basis (which occurs in video game mechanics when you look around) you use matrices whose ...
c++ - Handling entities in a game - Stack Overflow
2014年6月5日 · As a small exercise I am trying to write a very small, simple game engine that just handles entities (moving, basic AI etc.) As such, I am trying to think about how a game handles the updates for all of the entities, and I am getting a little bit confused (Probably because I am going about it in the wrong way)
2D vector modelling for game development - Stack Overflow
2010年1月17日 · As far as 2D vector game programming goes, it usually is the domain of Flash and Flex. Still SVG and loading it via Cairo seems to be a viable solution. Although I'd take care to make sure that you have hardware acceleration enabled (OpenGL backend preferably).
2d - Vectors games dev - Stack Overflow
2023年4月24日 · can someone explain to me not in "mathematical terms" but in practice, that is, the application of a vector in a 2D plane for video game development? Because until now I had the belief that a vector was generally a point, that is, the tail of the vector taken as a reference on the 2D plane of a game engine, plus the displacement from this point.
2d game vector movement C# - Stack Overflow
2013年12月17日 · A vector of the same direction and length of one unit would therefore be the vector with both components divided by the length of 4.2: Direction Vector of length 1: (0.95 / 0.30) As your player is fast and moves two units, it would be double length:
Does Android's "Game Rotation Vector" sensor ignore rotation …
2015年4月20日 · For my device, Game Rotation Vector started out good, but accelerated and finally drifted more than 400 degrees over the course of an hour. Secondly, and even more disturbing, it does not seem to ignore magnetic fields, contrary to …
how does normalizing vectors go with game programming
2014年2月25日 · Multiply a unit vector by five, and what do you have? A vector pointing five units in that direction. As a practical example, let's say I'm writing a camera system for a simple game: two cars race against each other on a straight track. The camera should orbit around the player's car while looking in the direction of the opponent.
unity game engine - What does vector minus vector actually mean …
2014年3月6日 · But if you're gonna create a 3D game world (which kinda is the purpose of Unity3D), Vectors are essential. Depending on the game, an AI can be created without using Vectors, but if the AI character can move in some game world, you're back at needing vectors. Don't get me wrong, I know everyone has to learn.
2D Vector rotation in Java - Stack Overflow
2013年10月3日 · If that happened the movement vetor gets rotated. The next two statements are checking the up and down key and appliing the speed to the movement vector by using this formula: x = cos a * (l + speed) y = sin a * (l + speed) where a is the angle of the movement vector and l is the length of the movement vector
Math used in 3D (Game) Engine Programming - Stack Overflow
2009年8月24日 · I'd like to get an idea what kind of math is typically necessary for 3D game engine programming? Any specific math (such as vector geometry) or calculation algorithms (such as fast fourier transforms), or is this all abstracted away with DirectX/OpenGL so that highly complex math isn't really necessary any more?
