Data Structures

struct  ScriptAllocator
 In the memory allocator for Squirrel we want to directly use malloc/realloc, so when the OS does not have enough memory the game does not go into unrecoverable error mode and kill the whole game, but rather let the AI die though then we need to circumvent MallocT/ReallocT. More...

Detailed Description

the implementation of the Squirrel class.

It handles all Squirrel-stuff and gives a nice API back to work with.

Variable Documentation

◆ _squirrel_allocator

ScriptAllocator* _squirrel_allocator = nullptr

In the memory allocator for Squirrel we want to directly use malloc/realloc, so when the OS does not have enough memory the game does not go into unrecoverable error mode and kill the whole game, but rather let the AI die though then we need to circumvent MallocT/ReallocT.

For the rest of this code, the safeguards should be in place though!
