Snowball Event
Snowball Event
Starting Trigger State and Update State
On start, turns on physics to set snowball then sets it back to kinematic. Waits for player trigger to start event to save performance.
Whole view of tracking state
On start grab starting position to use for Z transform freeze
Set snowball trail position based off position of snowball so that it's always on bottom of snowball no matter the size and then lock Z position.
Lastly check velocity tolerance
Check if max scale is reached and if not then add to scale but if so then move on. Animator triggers for player to push and stop pushing snowball
Set size multiplier of particle emission and radius so that it scales properly with snowball scale
Check if grounded if and not then stop particle system. Scale raycast ground checker to scale of snowball.
Trigger system to detect if snowball is melting due to flame object
Snowball Event
This script was a fun one to play with. It was made using Bolt's visual scripting tool for Unity.
Snowball behavior as follows
-On start, turns on physics to set snowball on ground then turns it back to kinematic
-Snowball scales up by taking scale and adding to itself if the velocity is greater than tolerance
-Scale checks to stop if desired max scale is reached
-Mass and Drag scale appropriately based off scale
-Particle trail plays only when velocity tolerance is greater or equal to and pauses when not
-Ground detection raycast to detect when to pause particle system if snowball is no longer touching ground.
-Ground detection raycast scales length based on scale of snowball
-Snowball also shrinks if object with tag enters trigger to "melt"
