Blender character won't animate

After studying the 3rd person tutorial (Lerpz), I made my own custom character in Blender and copied the .blend file into the assets folder. I had to scale it 0.1, 0.1, 0.1 since it was waaaay too big compared to Lerpz.

Lerpz had many animations, in comparison I only had few animations. I made sure to totally replace Lerpz with my custom character and set the animations for the actions which I had:

walk (frames 1-40)
run (frames 50-69)
jump (frames 90-115)
idle (frames 70-90)

Now when playing the character it jumps (w/o animation) and slides across Lerpz’s environment, but it doesn’t walk properly. On closer inspection it looks to be wobbling a bit, which means it’s trying to complete an animated cycle, but isn’t given enough time.

So I think it maybe only some scaling factor which needs to be set, but I don’t know which numbers to tweak.

Given the data I have above, how do you think I should tweak my blender character so it can at least walk, run and jump around like Lerpz? Thank you.

Are you using the same names for your animations as the ones that are used in the script?
