CollisionsBox Box IntersectionVersion 1.00 - VirtoolsCategorized in Collisions/Intersection DescriptionApply to a BEOBJECT.Detects the collision between two 3D entities at the box level. Box Box Intersection.cmoTechnical InformationIn: triggers the process.True: is activated if the 2 entities are in intersection.False: is activated if the 2 entities are not in intersection.Entity 0: first entity to be tested.Entity 1: second entity to be tested.Hierarchy 0: specify whether to concider the bounding box of the first entity and its children, or just the bounding box of the first entity.Hierarchy 1: specify whether to concider the bounding box of the second entity and its children, or just the bounding box of the second entity.This building block detects the collision between two entitys bounding boxes.Warning- This building block tells at a given time if the object 1 is touching or not the object 2.If you need to execute this test every 5 rendering process, you should then loop this building block with a 5 frame link.If you need to execute this test at each rendering process, you should then loop this building block with a 1 frame link.碰撞盒盒相交在Collisions/Intersection中将其分类描述适用于行为对象在一个立方空间内检测两个三维实体的碰撞Box Box Intersection.cmo技术信息In：触发该进程True：如果两个实体交叉则被激活False：如果两个实体没有交叉则被激活Entity 0：第一个受实验的实体Entity 1：第二个受实验的实体Hierarchy 0：明确指出是否考虑第一个绑定实体和它的子节点，或者只是第一个被绑定的实体。Hierarchy 1：明确指出是否考虑第二个绑定实体和它的子节点，或者只是第二个被绑定的实体这个BB表示是在两个绑定的实体之间实现的碰撞。警告这个BB告诉我们在给定的时间内，如果对象1被接触不再是对象2。如果你需要执行这个测试每5个渲染进程，你就必须每5帧循环一次这个BB如果你需要执行这个测试在每帧中，你就需要每帧循环一次这个BBBox Face IntersectionVersion 1.00 - VirtoolsCategorized in Collisions/Intersection DescriptionApply to a BEOBJECT.Detects the collision between the first entitys bounding box and each faces of the second entity.

Technical InformationOn: activates the process.Off: deactivates the process.Collision Occured: is activated when a collision occurs.No Collision: is activated while no collision occurs.Geometry Precision: you can force a geometry precision for all the obstacles or use the attributes specified precision with the Automatic value.Detection Tests: the maximum number of tests to be performed in addition to the initial one, to determine if a collision occured.

BodyPart Touched：角色的碰撞部位Touched Obstacle：3D实体接触的位置（如果你具体指出碰撞的层级关系父节点将被重新设置）Touched Sub Obstacle：3D实体接触的部位（在碰撞中重置精确的对象）不像“DetectCollision”行为交互模块，“Character Prevent From Collision” 如果你想要碰撞每帧都被测试，不需要循环。这个附属的角色通过设置“Moving Obstacle”的属性来给定，但是对每个你想要躲开的对象，这个对象需要被分配属性给Fixed Obstacle或者Moving Obstacle警告这个BB已经废旧了Collision DetectionVersion 1.00 - VirtoolsCategorized in Collisions/3D Entity DescriptionApply to a 3DENTITY.Detects the collision between the 3D object and other 3d object declared as obstacles.
