I have a fighter jet in my game, and normally it flies fine. After about 30 minutes to an hour into the server’s lifetime, all of the jets in the game start moving at about 30% their normal speed. I suspect this is because of garbage collection issues (its tycoon game, lots of droppers) that are reducing the heartbeat speed which I will need to fix.
That aside, is there any way I can make this vehicle less affected by this issue?
Summary of script below:
-
line1: function header, function is tied to runService.Heartbeat
-
health mechanics: spin plane and point downward while heath is zero
-
throttle: increase or decrease throttle based on inputs
-
speed increment: gradually increase plane’s speed value to meet throttle
-
ratio calculation: flightspeed is the speed the plane needs to fly. this ratio is determined by how close the plane’s speed is to reaching the flght speed
-
lerp the plane’s velocity to its current speed
-
apply torque based on the flight velocity, and apply direction based on camera direction
-
tilt the plane into the depth of the turn
-
raycast below, if ground is found then deploy the landing gear
-
set engine sound playback speed to the throttle
-
toggle particle effects in the engine based on throttle
-
prevent welded player from gaining networkOwnership of the plane
-
fire the guns if mouse is down
-
refill bombs when empty
