How do I make my movement with inertia

Hello. I'm new to Construct.

Tried to make their own movement. Allows you to move a sprite on the horizontal axis from left to right. This is not a problem. But I do not understand how to make a smooth change of direction (light inertia)?

Inertia the same as in the standard platformer.

Whatever the object was moving at a constant speed, but changed direction or stay smoothly.

Please tell me how can I solve this problem without the use of behavior platformer.

Sorry for my english

You could use lerp (linear interpolation) for this, but you could also program it yourself

Create a global variable speed

on right arrow down - sprite set x to sprite.x+speed

add a subevent

system compare variable speed is less than 10 - add 1 to speed

on left arrow down - sprite set x to sprite.x+speed

add a subevent

system compare variable speed is more than -10 - subtract 1 from speed

X on right arrow down (so inverted statement)

X on left arrow down (so inverted stament)

subevent

system speed is between -10 and -1 - add 1 to speed

system speed is between 1 and 10 - subtract 1 from speed

Doesn't the 8Direction behavior already have settings for that, like acceleration, deceleration, etc?

Thank LittleStain, will experiment

Was wondering how to make the controller without using a standard behavior
