vector - Help With Small C++ Game - Stack Overflow
Feb 9, 2011 · I'm writing a game of solitaire that runs in the terminal. As of now, the program compiles and runs and gives the player four cards, placed in four columns and allows them to press 0 for more cards, which are added onto the columns. As the column grows, it's output should be placed in a vector (actually, a vector of vectors).
vector - Game enemy move towards player - Stack Overflow
Apr 12, 2010 · The vector from the player to the enemy is: Player - Enemy or (10, 10) - (20, 10) = -10, 0 Normalising this vector gives you the unit vector, or direction. Which in this case is -1, 0. Multiple the unit vector (which is the direction remember) by a scalar value each frame and the enemy will move towards the player.
What is the need for normalizing a vector? - Stack Overflow
Apr 4, 2012 · 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 ...
2d - Vectors games dev - Stack Overflow
Apr 24, 2023 · 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.
How to create a directional vector that moves a certain entity to a ...
Feb 27, 2021 · Let's say the ball's position will be denoted by a 2D vector, denoted P. P = [P1, P2] To move this P in a 2D plane, you need a kind of push or force or whatever that changes your vector position and yields a new vector as a position: P#1 = P#0 + Vchange P#1: Position at T=1; P#0: Position at T=0. Now
c++ - Handling entities in a game - Stack Overflow
Jun 5, 2014 · 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)
C# 2D Vector Graphics Game using DirectX or OpenGL?
Oct 21, 2010 · I wanted to use C# as that is what I use for work, and have become vary familiar with. I have worked with both DirectX and OpenGL in the past, but mostly in 3D, but now I am interested in writing a 2D game with all vector graphics, something that resembles the look of Geometry Wars or the old Star Wars arcade game. Key points I am interested in:
how does normalizing vectors go with game programming
Feb 25, 2014 · 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.

Sep 10, 2011 · The direction of the car, the velocity and the acceleration are all 2-dim vector. Their directions are independent generally. However, for your car game those three vectors are in the same direction: the velocity is in the direction the car is pointing and so is the acceleration from the back wheels. Things are a bit more subtle with the steering.
