Aim Assist system for Unity that increases assist strength the closer aiming is to the target.
The GetAssistedAim() function in AimAssist.cs receives the raw aim vector as an argument. This function returns the modified aim-assisted vector. If aiming angle is within the user-set maximum threshold, then this vector will be corrected towards the nearest target (in angle).
- Add the AimAssist.cs script to the player game object.
- Set up assist parameters:
- Aim Assist Strength: Animation curve to define strength of aim assist in relation to angle towards nearest target. Best to have the strength be 1 at 0 degrees-from-target and a gradual fall-off toward 0 as the angle approaches the MaxAngle.
- MaxAngle: Maximum angle at which to assist aim, if angle-from-nearest-target is greater than this value then the assist strength will be 0 and the assisted aim will be equal to the raw aim (function argument).
- In your player controller, substitute the player input aim for the output of the GetAssistedAim() function. This function requires a List containing all the transforms of the targetable objects in the player character's vicinity as well as the raw player input aim vector.
- If more/less aim is needed then modify the y values of the Aim Assist Strength curve.
- If you need the assist to help with targets further away/closer to the player's raw aim input then increase/decrease the MaxAngle value.
