Bend by Object

Bend by Object allows you to change the angle of scattered items so that they rotate away or towards a selected object. It's ideal for illustrating objects interacting with grass or rugs with many other possible applications. To use it:

• Use the Object property to select an object from the scene that will be used to affect the angle of scattered items.
• Use leanOutAmount to change the amount objects will bend. Negative values lean away from the object and positive values lean towards the object. 
• Use leanOutDistance to control the distance from the object that the angle change affects. The effect will falloff until it reaches this distance.
• Use randomWiggle to add some rotation variation to the items that are affected by the bend effect.

Effect Script:

Vector vec1  =  object.position - fpItem.position;
real angle = atan2(vec1.x,vec1.y)-degtorad(90);

real lengthVec = length(vec1);
real leanOutX = easeIN( length(vec1),Lean_Out_Distance,0,fpItem.rotation.x,sin(angle+degtorad(randomReal(-randomWiggle,randomWiggle)))*Lean_Out_Amount);
real LeanOutY = easeIn( length(vec1),Lean_Out_Distance,0,fpItem.rotation.y,cos(angle+degtorad(randomReal(-randomWiggle,randomWiggle)))*Lean_Out_Amount);

fpItem.rotation.x = leanOutX;
fpItem.rotation.y = leanOuty;
