When i try to test my project the player moves but is stuck in the idle animation
Ok, so the idle state itself should contain your entire blendspace animation sequence. You don’t need any other states like walk or run or anything, that is the point of a blendspace. Delete the transition lines and walk state. Goto the idle state and create a blendspace player which accepts a float input (speed, in this case) and outputs an animation to play from the blendspace based on the inputted speed to the final animation state node which actually plays the animation. It should go like this, Speed → Blendspace player → Final animation state.
