**The power of computers is limited**, [Alan Turing](turing.md) mathematically proved that there exist problems that can never be completely solved by any [algorithm](algorithm.md), i.e. there are problems a computer (including our [brain](brain.md)) will never be able to solve (even if solution exists). This is related to the fact that the power of mathematics itself is limited in a similar way (see [Godel's theorems](incompleteness_theorems.md)). Turing also invented the theoretical model of a computer called the [Turing machine](turing_machine.md). Besides the mentioned theoretical limitation, many solvable problems may take too long to compute, at least with computers we currently know (see [computational complexity](computational_complexity.md) and [P vs NP](p_vs_np.md)). **The power of computers is limited**, [Alan Turing](turing.md) mathematically proved that there exist problems that can never be completely solved by any [algorithm](algorithm.md), i.e. there are problems a computer (including our [brain](brain.md)) will never be able to solve (even if solution exists).

Computing Euclidean distance requires multiplication and most importantly [square root](sqrt.md) which is usually a pretty slow operation, therefore many times we look for simpler [approximations](approximation.md).

- **Do NOT fucking spam electro** -- this will make you instantly hated, and rightfully so. Not only is it lame, annoying, makes you easy to kill (opponent can explode your electro balls), enforces more use of electro (electro is countered with electro) and makes the game lag, it can also hurt your teammates, even in no self/team damage modes (as opponents may explode the electro you spray around). Use it appropriately. - **Do NOT fucking spam electro** -- this will make you instantly hated, and rightfully so.

- **Learn the weapons and make binds for each one**: learn what every weapons does (good mode for this might be clan arena in which you have all the weapons from the start), bind each one around the movement keys -- it's essential you can switch weapons quickly as the game is designed to reward comboing (the most basic combo is devastator/vortex/mortar). Also note that almost every weapon has a **secondary fire**, for example crylink's primary fire just shoots bouncing balls while the secondary fire shoots a suction ball that can toss enemies out of the map or can be used to accelerate yourself. With devastator (rocket launcher) holding left mouse button allows **guiding the rocket**, right mouse button explodes the rocket in air -- learn this! Then you can easily kill enemies behind corners or flying in air. - **Learn the weapons and make binds for each one**: learn what every weapons does (good mode for this might be clan arena in which you have all the weapons from the start), bind each one around the movement keys -- it's essential you can switch weapons quickly as the game is designed to reward comboing (the most basic combo is devastator/vortex/mortar).

- **Learn the movement**: movement is essential in Xonotic, firstly you should learn extremely basic techniques like bunnyhopping, strafe jumping and in-air controls, and secondly you should learn using weapons for movement (blaster jumps, rocket jumps, crylinkg for acceleration and climbing walls, ...). This is important not only for quick relocation, taking shortcuts, dodging enemy fire and quickly running away from enemies, it will also save you from falling into pits. - **Learn the movement**: movement is essential in Xonotic, firstly you should learn extremely basic techniques like bunnyhopping, strafe jumping and in-air controls, and secondly you should learn using weapons for movement (blaster jumps, rocket jumps, crylinkg for acceleration and climbing walls, ...).

- **Unpredictable movement and positioning is key** to avoiding damage: nubs think that when they move fast they won't get hit -- this is only partially true, it is about just as important to move unpredictably and avoid spots that get regularly spammed by enemies. When you move from point A to B on a map and the enemy sees you doing so, you should take a randomly long short pause in doing so, or maybe even switch direction completely, otherwise he can quite accurately predict when and where you'll appear at the destination and kill you with prefire. It's a great advantage if your opponent doesn't know where you are. - **Unpredictable movement and positioning is key** to avoiding damage: nubs think that when they move fast they won't get hit -- this is only partially true, it is about just as important to move unpredictably and avoid spots that get regularly spammed by enemies.

- **Use machine gun (MG) secondary to finish off low HP enemies**: MG is [hitscan](hitscan.md), i.e. it hits instantly on a distance and its easier to hit with than vortex (which fires just one strong shot) -- the secondary fire has no bullet spread unlike the primary fire, so it's ideal to just deal quick small hit that's enough to finish someone. But watch out, some people bitch about using MG this way being too nub, going for slap will entertain the audience better.
