game programming

A mesh collider O a. Is as accurate as the triangle count on the mesh O b. Is the only viable option for complex meshes such as player characters Oc. Is the only way to get headshots to work O d. Is faster than a box collider Planning Al works by: O a. Executing random actions until the desired precondition is found O b. Executing all actions sequentially until the desired precondition is found Oc Matching preconditions to post-conditions until an action is found where all preconditions are met Od Matching preconditions to post-conditions until all actions are successfully completed Adding two vectors gives a: O a Vector O b. Hypercube Oc Plane O d. Point In an Al system that uses planning, when performing an action we start by: O a. Adding the action to be performed to the action list O b. Clearing the action list Oc Scanning all post-conditions for the desired result Od Scanning all pre-conditions for the desired result
