Lerp smoothly continuosly

pontino

Hello, how to lerp rotation locally? Im lerping with self.rotation = lerp(self.rotation, self.velocity.angle() + 1.5708, 0.1) but when i reache the angle 359->0 he lerp faster to the other direction instead of going from 359 degrees to 0 degrees smoothly.. How solve the issue? He have to lerp ever to the shortest angular distance..

Use quaternions and spherical lerp; here's an example I used for smooth mouse look

var hor_quat = Quat(Vector3(0, -1, 0), deg2rad(target_look.x))
var ver_quat = Quat(Vector3(-1, 0, 0), deg2rad(target_look.y))
var cur_quat = Quat(looking.global_transform.basis)
cur_quat = cur_quat.slerp(hor_quat * ver_quat, delta * cam_smooth_speed)
looking.global_transform.basis = Basis(cur_quat)
