How is the render loop in a game solved?
We typically still have one loop. input, update, render, repeat. Collision problems as you mention are solved by using a collision detection method that calculates the area that the object would pass through, eg. resolving for X= [0 to 17].
Is it possible to thread a render loop?
You can thread things and separate logic updates and rendering, but it’s tricky to get right and large portions of game loops are inherently single-threaded. Instead, look into advancing your game loop using a delta time to scale things so that the logic update is largely independent of the machine’s ability to chomp through the frames.
How does a game loop work in gameloop?
A game loop runs continuously during gameplay. Each turn of the loop, it processes user input without blocking, updates the game state, and renders the game. It tracks the passage of time to control the rate of gameplay.
Is it easy to make a Tetris render loop?
It’s easy if your world boundaries are simple. E.g. in Tetris, the blocks are only allowed to move left and right until they hit the sides, and it’s easy to test if the bottom-most coordinate is hitting the “ground.”
What does the logical LOOP DO in XNA?
The logical loop (Update method in XNA) will basically handle updating positions and what not, while the display loop (Draw method in XNA) will draw everything to the screen. As for collision detection, I would personally localize that to your ball.
Are there any games that use dedicated renderer threads?
Breakout and “Record GL app” use dedicated renderer threads, and they also update animation state on that thread. This is a reasonable approach so long as game state can be updated quickly. Other games separate the game logic and rendering completely.
Which is the best way to implement a game loop?
A very popular way to implement a game loop looks like this: There are a few problems with this, the most fundamental being the idea that the game can define what a “frame” is. Different displays will refresh at different rates, and that rate may vary over time.
How is update called in the game loop?
Once per frame, the game loop walks the collection and calls update () on each object. This gives each one a chance to perform one frame’s worth of behavior. By calling it on all objects every frame, they all behave simultaneously. Since some stickler will call me on this, yes, they don’t behave truly concurrently.
