I’m creating a game that will involve racing and would like to know if theres anyway to handle drifting so that when a user goes around a corner at a high enough speed with the steering further than a certain amount the back wheels will lose grip/friction and slide (laterally I guess?).
In the desert racing game example I noticed in the C++ theres some stuff they play with to do with friction and wheels and lateral movement.
I got my tire array in my WheeledVehicled class and then casted to the back wheels of class VehicleWheel but theres nothing I can set there and its a data only class anyway and even going into the BP editor theres no variables I can set or functions i can override.
So is there any way I could acheive the ability for a car to lose traction and be able to tune it for a smooth racing experience or do I need to delve into the C++ for the VehicleWheel class (would even know where to begin unfortunately). I cant set the lat/long stiffness or anything during runtime.
Also the tiretype cant be changed during runtime since thats just a dataasset but it holds a variable called “FrictionScale” 2.0f at the front and 3.0f at the rear.
Tips, suggestions? Cant find much info on this.
Edit: If I try changing the wheel array using SetElem on index 2 and 3 (rear wheels) to a new type (a low friction setup) it crashes the editor with the following so obviously that cant be done either changing the array manually before runtime gets the effect i want though, slippery rear tires.
