Dashing based on movementinput

Previously I only could dash forward based on the players forward vector, but now I want to dash based on ht players input direction. I tried this code but it just made me fly out the map:

void AJuniorProgrammerTestCharacter::Dashing()
{
	//const FVector ForwardDir = this->GetActorRotation().Vector();
	const FVector Dash = this->GetCharacterMovement()->GetActorLocation();
	if (GetCharacterMovement()->Velocity != FVector::ZeroVector) 
	{
		LaunchCharacter(Dash * DashDistance * DashSpeed, true, true);
	}
	

}

the if statement is for when the player is not moving, the dash will not activate. I learned this recently here

Sounds like you want to bind variables to both MoveForward and MoveRight input axes and then read the value of those to determine what direction your input is in.

yea im trying to get their vectors and then implement the dash on it. This means that regardless of the player rotation or where its facing, i can dash based on the movement input, but i dont know how to call it

Wouldn’t it be better to use some specific key which triggers the dash, which then checks the movement direction if your character?

Oh. And another thing.
Add a FVector(0.0f, 0.0f, 20.0f) or something similar to your dash.
It adds a little height to your dash.
Else your character will directly collide with the floor again and stop.

sorry im quite new, how would i do that? I am already using the left shift key as the trigger for the dash

Write something like DashSpeed + FVector(0.0f, 0.0f, 20.0f)

alright added, but the directional dash is still a problem

Does LaunchCharacter multiple the characters current velocity by that input parameter?
If your char is flying out of the map then you are pushing in too big a value.
Normalize the current velocity and use that for your dash direction and multiply by your dash amount.

I finally did it haha, it was GetLastInputVector(). As shown below:

void AJuniorProgrammerTestCharacter::Dashing()
{
	
	const FVector Dash = this->GetCharacterMovement()->GetLastInputVector();
	if (GetCharacterMovement()->Velocity != FVector::ZeroVector) 
	{
		LaunchCharacter(Dash * DashDistance * DashSpeed, true, true);
	}
	

}

This allowed my character to dash based on the direction of my input
