How am I able to make sonic like contols?

I don’t know junk about coding. I was able to make a script to make him move. I worked, but i want do better with with

I don’t know how to explain it clearly, but I want to be able to make my characters physics like sonic adventure. Like making his speed and animation eases faster and shifting animations while doing so. I want to make him change to 3 animations while he runs. Jogging when he is slow, Running when he goes faster, and sprinting when at full speed.

Anybody got any tips or ideas?

Yes, but i suggest you learn scripting first. As things get more complex and you want more features you will need to understand at least the basics so that you know what you are looking for if you cant figure something out. There have been many questions regarding the feature you desire.

“ease in” and “ease out” are achieved by lerping.

basic “if” statements would play those specific animations when a speed value crosses a threshold you desire.

if(speed > 0.5f && speed <= 0.75f){  
//play jogging
}else if(speed > 0.75f){
//play sprinting
}
