<aside> ⚡ script "core_getPlayersInRadius" (int radius, int flags, int pointer, int unused)
</aside>
This script is a more robust version of [core_checkDistance](<https://mm8bdm.notion.site/core_checkDistance-c80818500c6c43e59e7c42aa5215f2d1>), providing the number of players within a given radius of the calling actor, as well as providing flags to tweak behavior.
radius: int - The radius of the check, in map units.flags: int - A bitwise flags field. Flags should be combined as follows: FLAG_1|FLAG_2. Acceptable flags are below:
PRF_CUBE: Changes the detection zone to a cube instead of a sphere.PRF_CHECKCOLLISION: Changes the detection zone to factor in the radius of players.PRF_CLOSESTPOINTER: Will set a given actor pointer on the calling actor to the closest player found.<aside>
🚨 Note that as of V6B, PRF_CLOSESTPOINTER has improper and unexpected behavior, tending to prefer players with a lower player number or players which are more perpendicular to the calling actor. This behavior will be cleaned up in a later version!
</aside>
pointer: int - The pointer field to set if using the PRF_CLOSESTPOINTER flag.Returns the number of players whose origin is within the specified radius.
Below is a minimized example of Rush Jet showing how the PRF_CLOSESTPOINTER flag can be used in practice.
Look:
RUSH III 1 A_JumpIf(CallACS("core_getPlayersInRadius", 80, PRF_CLOSESTPOINTER, AAPTR_TRACER) > 0, "Melee")
RUSH I 0 A_CountDown
Goto Look
Melee:
RUSH G 0 A_GiveInventory("RushJetActivate", 1, AAPTR_TRACER)
stop
Below is an example of how PRF_CUBE and PRF_CHECKCOLLISION are used, in this case to disallow Concrete Shot from spawning inside players and blocking them.
Spawn:
CONC D 0
CONC D 0 A_JumpIf(CallACS("core_getPlayersInRadius", 20, PRF_CUBE|PRF_CHECKCOLLISION) > 0, "Death")
CONC D 1
CONC E 0 A_ChangeFlag(TOUCHY, false)
CONC E 0 A_ChangeFlag(MISSILE, false)
CONC E 0 A_ChangeFlag(SOLID, true)
CONC EF 64
Goto Death
Death:
CONC B 0 A_NoBlocking
CONC FG 3
stop
