Making a Pickup Bounce

[LOZ_98]

It seems like all Bounce flags and properties affect only missiles / projectiles, Is there a way to do it with Pickups ?

[Matt]

What kind of bounce specifically do you want? (and why is a pickup bouncing around anyway?)

There might be a way to fake it with A_ChangeVelocity and CheckMove.

It's a pickup that the player drops after he gets damaged, I want it to bounce after falling, I want the bounce strength to change depending on how fast the item falls, what does CheckMove do?

[Matt]

CheckMove checks if an actor can move to a given set of XY coordinates, letting you check whether there's a blocking actor or line. I mention it in case you needed horizontal bouncing.

For vertical bouncing off the floor only it can be much simpler:

Code: Select all

override void Tick(){
    // if it's on the ground and moving downwards,
    // make it move upwards instead but not as fast
    if(
        vel.z<0 &&
        pos.z<=floorz
    ){
        vel.z=-vel.z*bouncefactor;
    }
    // do all the other ticky stuff
    super.Tick();
}
