2 iterations will likely cover most cases (unless the time step is really long).Įnable for One Way Platforms - Should the motor check for one way platforms? Uncheck this if there aren't any, the motor will be more efficient. Lower numbers mean more performant but at a cost of potential position loss. Number of Iterations - The number of iterations the motor can take to resolve the final position during a tick. Half distance of the Environment Check Distance is probably pretty good. This is used to prevent catching matching edges of box colliders (or tiles). Minimum Distance From Env - This is the minimum separation between the motor and surrounding environnment. These are environments that shouldn't be able to move into the player.Įnvironment Check Distance - This is how far out the motor will check for the environment. Static Environment Layer Mask - This tells the motor what layer collisions to consider the environment (to determine if on the ground, wall, or corner). PlatformerMotor2D Inspector Properties General The motor uses the bounds of the Collider2D to understand where to check for contact with surfaces. The motor requires that a Collider2D be present on the GameObject. Requirements of PlatformerMotor2D BoxCollider2D There is no guarantee made that variables names won't change and if they do then the old values will be lost in the inspector. When upgrading take a note of your current motor values before upgrading.

For more complicated interaction, interface with PlatformerMotor2D's members and methods. Setupįor immediate player support, drop the Basic Player Controller prefab into the scene and set the Static Environment Layer Mask field. Please open up an issue if there are any problems. This isn't a perfect solution but allows it to work within Unity's physics system.Īlso I am no longer using the platformer controller in my own personal projects so it's not getting the personal testing it deserves. Make sure Environment Check Distance and Minimum Distance From Env need to be increased from what they were in Unity 5.2 (default is 0.08 and 0.04). Unity 5.3 appears to change the behavior of ray/boxcasts which PC2D relies heavily on.

If you'd like the most up to date version (which is the most cool), then pull the repo or download it here and copy the files in Assets to your project's Assets folder. Includes a player controlled prefab that can be dropped into any scene for immediate support. Here, if the script was attached to the camera, a ray is casted from the camera's position, taking the camera's relative down direction, to obtain the information of the ground below it.A customizable 2D platformer motor that handles mechanics such as double jumps, wall jumps, and corner grabs. If(Physics.Raycast(transform.position, -transform.up, out hit, distance, mask))įorward = Vector3.Cross(transform.right, hit.normal) One of the ways to get a ground's normal is by using Physics' API functions such as Raycast, Spherecast, Boxcast, etc., where you can obtain the RaycastHit information of the ground you are contacting.įor the sake of a simple example, you could try this with Raycast: public class GetForwardVector : MonoBehaviour So, both vectors you'll have to pass as parameters in the function are the camera's transform.right and the plane's normal (as an Y vector) as A and B respectively, so you get a forward vector parallel to the ground's plane.

What the cross product gives you, is a vector C perpendicular to 2 vectors A and B. The solution is as simple as using Vector3.Cross(Vector a, Vector b), it is not commutative, so you'll have to give the vectors in the correct order. So, you want to get a forward vector parallel to the ground plane relative to the camera's rotation, from what I can get.
