c# - Hit incoming missile (simple projectile missile) in Unity3D -


i want make surface air missile system in unity3d predict incoming missile position after time 't' , set interceptor missile angle , position in 3d coordinates hit incoming missile. using following function prediction of incoming missile.

    void updatetrajectory(vector3 initialposition, vector3 initialvelocity, vector3 gravity) {     int numsteps = 500;      float timedelta = 1.0f / initialvelocity.magnitude;       linerenderer linerenderer = getcomponent<linerenderer>();     linerenderer.setvertexcount(numsteps);      vector3 position = initialposition;     vector3 velocity = initialvelocity;     (int = 0; < numsteps; ++i)     {         linerenderer.setposition(i, position);           position += velocity * timedelta + 0.5f * gravity * timedelta * timedelta;         velocity += gravity * timedelta;     } }

i using line renderer visual trajectory display. can hit missile @ few position means :p have adjust manually. sam missile system set angle can't set exact time , velocity hit missile.

you need professional: exponential curve fitting.

you points curve , find coefficients of curve extrapolate next point. algorithm seems little linear whole curve true latest points , not enough.

alos known non-linear regression.

SPSS keyboard combination alters encoding -

my question not have programming practical issue on spss. accident keyword combination cannot remember because did not intend press changed encoding in spss , text in data in different language english shown small boxes. nevertheless, when kind of analysis performed different language text shown in output. does know reason? tried change encoding did not produce result. first, @ edit > options , see whether setting unicode or locale. might fix it. if have text in multiple languages, want unicode. otherwise, may have specific locale set wrong. can change set locale, need know locale want use.
