i keep geting the same error massage (invalid operands ‘Vector3’ and ‘Nil’ in operator ‘*’)every time i run the scene

direction = direction.normalized()
h_velocity = h_velocity.linear_interpolate(direction * speed, h_acceleration * delta)
movement.z = h_velocity.z + gravity_vec.z
movement.x = h_velocity.x + gravity_vec.x
movement.y = gravity_vec.y

the erorr is in movement.z

From what I can tell, one of those variables doesn’t have a value (or rather, the value is null). The problem may be in the assignment to the hvelocity variable, in the parameters to the linearinterpolate() function.

Based on the code snippet you posted, your speed variable in the script is not initialized before you execute the hvelocity line. Adding speed = 50 or whatever to your script should resolve your issue.

If speed is already set to a value in the script, you will need to post more code because those aren’t the lines where the error is happening.
