I will share with all this utility to generate random locations to be used as spawnpoints or whatever you want.
With this you can get random spawns with a minimum distance between each one.
I know there's other alternatives but didn't help me

I'm using some checks to be sure the location will be suitable to spawn a player or and entity without problems:
- Minimum distance between points on first pass
- Check for empty point contents
- Check for hull (HULL_LARGE)
- Avoiding locations near sky (250.0 units)
- Avoiding water and other surfaces on floor
- Visibility between consecutive points (to get "in map" points)
I tested this on some standard and custom maps without problems.
Sometimes you can get a location over a box but you can check that outside this utility. Also I worked to avoid ceiling locations.
I will be glad with feedback about useless locations (outside map, non stuck-free locations, etc).
Ideas and improvements are welcome too.
Here's an example on how to use the included file
PHP Code:
#include <amxmodx>
#include <superspawns>
public plugin_init()
{
// First we have to initialize the arrays and parameters
// The value 3500.0 is the minimum distance between points
// Nearest points will be found, but GetOrigin will erase points
// with less than 3500.0 distance with other used points and return
SsInit(3500.0)
// Let start scanning the map
SsScan()
// This call is to dump on server logs the origins found
SsDump()
// This command will call GetOrigin() to get a new location, then spawn a model (is't just an example)
register_concmd("spawnent", "spawnent")
}
public spawnent(id)
{
new Float:origin[3]
// SsGetOrigin() will return true if useful location was found
// will return false if there's no more usefull locations
if(SsGetOrigin(origin))
{
new ent = engfunc(EngFunc_CreateNamedEntity, engfunc(EngFunc_AllocString, "info_target"))
if(pev_valid(ent))
{
engfunc(EngFunc_SetModel, ent, "models/player/sas/sas.mdl")
engfunc(EngFunc_SetOrigin, ent, origin)
}
}
else
{
server_print("No more locations")
}
return PLUGIN_HANDLED
}
