# MapExecutions Decls

Location: `rs_streamfile/generated/decls/mapexecution/`

These decls are new to idTech8, and define object pools for hundreds of different entity types. It's unknown how important they are compared to the `aipoolnumbers` decls. If you ever run into a problem with entities not spawning or the game crashing when too many of an entity are spawned, consider experimenting with these files.
