<|im_start|>What is QuakeC?<|im_end|>
<|im_start|>assistant
<|im_end|>
<|im_start|>QuakeC is a scripting language developed by id Software for creating mods and gameplay logic in the Quake 1 game engine. It is a simplified version of the C programming language and is interpreted by the Quake engine.<|im_end|>


<|im_start|>user
<|im_start|>What are the basic data types in QuakeC?<|im_end|>
<|im_start|>assistant
<|im_end|>
<|im_start|>QuakeC primarily uses `float` for numerical values and `string` for textual data. It also has `vector` for 3D coordinates and `entity` to represent game objects.<|im_end|>


<|im_start|>user
<|im_start|>How do I declare a variable?<|im_end|>
<|im_start|>assistant
<|im_end|>
<|im_start|>In QuakeC, you can declare a variable using the type keyword followed by the variable name. For example, `float x;` declares a float variable named x.<|im_end|>


<|im_start|>user
<|im_start|>How do I write comments in QuakeC?<|im_end|>
<|im_start|>assistant
<|im_end|>
<|im_start|>You can use `//` for single-line comments and `/* */` for multi-line comments. For example:

// This is a single-line comment
/* This is a
multi-line comment */<|im_end|>


<|im_start|>user
<|im_start|>Tell me about control structures in QuakeC.<|im_end|>
<|im_start|>assistant
<|im_end|>
<|im_start|>QuakeC supports basic control structures like `if-else`, `while`, and `do-while` loops. The syntax is similar to C. For example, `if (x > 0) { /* code */ } else { /* code */ }`.<|im_end|>


<|im_start|>user
<|im_start|>How do I define a function?<|im_end|>
<|im_start|>assistant
<|im_end|>
<|im_start|>Functions in QuakeC are defined with a return type, name, and parameters. For example:

```
float MyFunction(float x, float y) {
  return x + y;
}
```<|im_end|>


<|im_start|>user
<|im_start|>How do I print to the console?<|im_end|>
<|im_start|>assistant
