I am making a Homing Missile that, when shot, executes A_HomingChase to follow any player other than yourself. Everything works except that the missile follows any nearby player, including you. I have the target being player.mo. Is it possible to make it distinguish between the firer and the target, and not chase after the firer?

I'm assuming you've set it to follow the object's tracer, which is set to a nearby player? The best thing you could do to set the tracer to a nearby player other than yourself is probably to use a Lua function that goes something like this: (I'm not sure if there's a non-Lua method to do this with)
Code:
-- Finds a player other than the object's target that's nearby, and sets it to the object's tracer
-- Var1 = distance limit
-- Var2 = if set, get the nearest player - if not, just take the first one in range
function A_FindOtherPlayer(mo, distlimit, nearest)
local distcheck = distlimit
for p in players.iterate do
if not (p.mo and p.mo.valid and p.mo.health) then continue end
if p.mo == mo.target then continue end
local newdist = P_AproxDistance(P_AproxDistance(p.mo.x-mo.x, p.mo.y-mo.y), p.mo.z-mo.z)
if newdist <= distcheck then
mo.tracer = p.mo
distcheck = newdist
if not nearest then return end
end
end
endIt's the maximum distance the player can be from the missile, yes. If you want a minimum distance you can change line 10 to:
if newdist <= distcheck and newdist >= nearest then
and line 13 to
if not (nearest & 1) then return end
and the upper 16 bits of var2 will be said minimum. But for the purpose you've outlined (just finding a player that isn't your target) it shouldn't be necessary.
if newdist <= distcheck and newdist >= nearest then
and line 13 to
if not (nearest & 1) then return end
and the upper 16 bits of var2 will be said minimum. But for the purpose you've outlined (just finding a player that isn't your target) it shouldn't be necessary.

MT_PLAYER is an object type identifier, not an object itself.
I didn't even notice there was a GIF in your last post since it didn't load on my end, lol. Could you post the script in question so I can see if it's really an issue with identification or if some other culprit may be the cause? 'Cus I can't think of anything wrong with the script I shared, but I also don't have a setup to quickly test it in.
Thanks, I fixed the GIF in the other post. Here's the LUA part:

No, you want its Var2 to be 1. HomingChase should go after the tracer, not the target, because the target is whoever fired it. A_FindOtherPlayer is specifically made to set the object's tracer for this reason.
