Автоматические реакции на приближение в After Effects

Обучение видеомонтажу в Adobe Premier и After Effect

Обучающие выражения:

INFLUENCE POSITION (ВЛИЯТЬ НА ПОЛОЖЕНИЕ)

nullPos = thisComp.layer("NULL").transform.position;
objPos = transform.position;
maxDist = thisComp.layer("CONTROLLER").effect("Max Distance")("Slider");
strength = thisComp.layer("CONTROLLER").effect("Strength")("Slider");
dist = length(nullPos, objPos);
dir = normalize(objPos - nullPos);
moveAmount = strength * (1 - clamp(dist / maxDist, 0, 1));
newPos = objPos + dir * moveAmount;
newPos;

INFLUENCE TIME REMAP (ИЗМЕНЕНИЕ ВРЕМЕНИ ВОЗДЕЙСТВИЯ)

nullLayer = thisComp.layer("NULL");
distance = length(nullLayer.position, transform.position);
maxDist = thisComp.layer("CONTROLLER").effect("Max Distance Time")("Slider");
strengthDist = thisComp.layer("CONTROLLER").effect("Strength Time")("Slider");
effectiveDist = clamp(strengthDist, 0, maxDist);
timeStart = 0;
timeEnd = 5;
clampedDistance = clamp(distance, effectiveDist, maxDist);
remapTime = linear(clampedDistance, maxDist, effectiveDist, timeStart, timeEnd);
remapTime;

EFFECTS ANGLE (УГОЛ ВОЗДЕЙСТВИЯ)

nullPos = thisComp.layer("NULL").transform.position;
objPos = thisLayer.transform.position;
angle = -radiansToDegrees(Math.atan2(objPos[1] - nullPos[1], objPos[0] - nullPos[0])) + 180;

EFFECTS OPACITY (ЭФФЕКТЫ НЕПРОЗРАЧНОСТИ):

nullPos = thisComp.layer("NULL").transform.position;
objPos = thisLayer.transform.position;
maxDist = thisComp.layer("CONTROLLER").effect("Max Distance")("Slider");
dist = length(nullPos - objPos);
opacity = 100 * (2 - 2 * clamp(dist / maxDist, 0, 1));
