moveTo() function jittery at certain speeds

by GilForumGuy · in Torque Game Builder · 03/29/2010 (11:16 am) · 4 replies

Hello,

I have been calling the moveTo() function and I notice that at slower speeds the motion of an object moving is just fine. For instance a velocity of 10 is just fine. But when I increase the velocity to 50. The motion of the object moving becomes very jittery.

Anyone else have this issue and found a possible resolution?

I'm using fairly high speeds (over 200) and am not seeing this issue. One issue to check: is your object mounted and/or does it have any mounted objects?

Thanks for your response. I don't have the objects mounted. I am beginning to think that it is something I am doing in my script code that may be causing the jittering.

I created a barebones project with an object moving and didn't notice any jitter. I'll do a few tests on my code and see how it goes.

Thanks.

Are you by chance calling the moveTo from the onUpdate callback?

I've seen things jitter when it gets called repeatedly - I imagine due to floating point errors introduced when objects are moving at high speeds.

I am calling moveTo() without the onUpdate callback. The object starts to move once it has been selected. I'll definitely keep what you said in mind though so I don't run into the same problem.
