Question What about Moving-Object Timers?

This is my first thread, I hope everything is fine!

Well... I don't know if anyone came up with this, but I discovered it myself.

Is it a good idea to make timers (including repetitive timers) based on MoveObject and OnObjectMoved? By making an object to move from (let's say) 0.00 / 0.00 / 0.00 towards 0.00 / 0.00 / 1.00 with a set speed of 1.00 units per second, OnObjectMoved is called after one second. Then you can make the object move back to 0.00 / 0.00 / 0.00 with the same speed when OnObjectMoved is called, so you got a nice 1 second repetitive timer. Also, you can set a very small interval by just calculating the distance you want it to travel within the given speed.
Example:
From 0.00 towards 1.00, for one second to pass, you need to set the speed to 1.00 units per second.
From 0.00 towards 1.00, for 100 milliseconds to pass, you need to set the speed to 10.00. units/s.
From 0.00 towards 1.00, for 100 microsecond to pass, you need to set the speed to 10000.0 units/s.

Of course, you can do per-player timers using MovePlayerObject and OnPlayerObjectMoved.

Are these timers a good idea for optimization and can they remain accurate when are 700+ players connected? I think normal timers are using much more resources to run compared to these which are just moving objects. Please, let me know your opinion!

Sorry for my English mistakes, I'm not a native-speaker.

Default Re: What about Moving-Object Timers?

Theoretically you can, but you would waste object slots. They also do not remain as accurate as timers if the server is under stress - objects will start to move slightly slower than on the client side.

Also I don't think they use less resources. They seem to be processed on every server tick, similar to how timers are iterated on every server tick. Additionally to that, objects and player objects are synced with players, so it creates network traffic for no good reason (which doesn't happen for timers).

If the default timers are not precise enough, there are plugins to solve this issue. Those usually use less resources than samp timers as well (for example this plugin, but there are a few more).
