task scheduler priority
Post Simulation step is supposed to be before heartbeat.
PostSimulation
The PostSimulation event fires every frame, after the physics simulation has completed. The deltaTimeSim argument indicates the time that has elapsed since the previous frame.
This event is useful for making final adjustments to the outcome of the simulation. Following this phase, the engine triggers the Heartbeat event.
repro:
local run = game["Run Service"]
local n = 200_000
run.Heartbeat:Connect(function()
local name = "heartbeat"
debug.profilebegin(name)
local a,b = 1,0
for i = 1, n do
a,b = b,a
end
debug.profileend(name)
end)
run.PostSimulation:Connect(function()
local name = "post simulation"
debug.profilebegin(name)
local a,b = 1,0
for i = 1, n do
a,b = b,a
end
debug.profileend(name)
end)
run.PreSimulation:Connect(function()
local name = "pre sim"
debug.profilebegin(name)
local a,b = 1,0
for i = 1, n do
a,b = b,a
end
debug.profileend(name)
end)
while true do
task.wait()
local name = "task.wait()"
debug.profilebegin(name)
local a,b = 1,0
for i = 1, n do
a,b = b,a
end
debug.profileend(name)
end
Expected behavior
it should come before
