unity3d - Move object in Unity 5.0 -

-

using unity 5.0 . write these codes move prefab:

gameobject policecarinstance = instantiate(policecar,enemyspawner.position, quaternion.identity) gameobject; rigidbody2d policecarrigidbody = policecarinstance.getcomponent<rigidbody2d>(); policecarrigidbody.velocity = new vector2 (0f, -10f);

when animator component of prefab disabled, prefab moves correctly when it's enabled, prefab doesn't move. animation 5 sprites of different states of police car's lights. here's pic of animator of prefab:

object animator

this code same properties , states works on unity 4.6 (even when animator component enabled) in unity 5 doesn't work!

is there changes in unity 5 influence in rigidbody2d component?

[C++][SFML 2.2] Strange Performance Issues - Moving Mouse Lowers CPU Usage -

-
i've been working on making 2d map editor past 2 weeks or so, , i've run strange problem. trying optimize code, example, making functions should've been functions begin with, did made cpu usage go through roof. i've tried commenting out different sections of code thought culprits (scrolling, rendering, other calculations) no avail. think issue might trying call things within different functions, sake of making modular possible, i'd functionality. the other major change i've made since file i'm comparing i've ported variables external cpp file, since having variables global makes lot easier use within different functions. simple issue, can't life of me understand why happens. with original code, around 2-3% cpu usage. new code, around 20-35%, but, if move mouse around, it'll drop around 6-8%. tl;dr: after trying optimize code using functions, i've somehow killed performance, , found strange quirk moving mouse reduces cpu usage.. /...
