Force and impulses

In this tutorial I (xtron) will explain how to use Prop/Body force and impulses

How to get the coordinates:

Create an item were the player/prop stands when it/he's geting pushed then you press ctrl+d ( duplciate it ) and drag it to the place where

he's going to get pushed to.

Lets say that blue dot is the player/prop and he's going to get pushed to the chair that got the X position -3.5, you replace “float afX”

with “-3.5f” and you're done.

And there you go, you just found out how to get the coordinates.

force/impulse:

I will use BodyForce for an example only, you can use PropForce exactly the same as BodyForce.

AddBodyForce(string& asName, float afX, float afY, float afZ, string& asCoordSystem);

This function will push the player in a certain direction and by using the method I showed you, you will get the coordinates.

We will use the same coordinates shown on the picture.

Lets say the player stands on the blue dot and is geting to the chair. you will need to modify the function like this:

AddBodyForce("Player", -3.5f, 0.0f, 0.0f, "world");

the player will now be pushed to the X coordinate -3.5. He will NOT move in the air unless you change the Y coordinate a bit.

If you move the chair upp a bit you will see that the Y coordinate will change. When you're done you need to change the code again

like this:

Lets say you moved the chair so Z is 2.0

AddBodyForce("Player", -3.5f, 2.0f, 0.0f, "world");

Now will the player fly abit aswell.

THIS CAN BE USED WITH

AddPropForce(string& asName, float afX, float afY, float afZ, string& asCoordSystem);

Aswell!

READ!: IF YOU'RE GONNA USE AN IMPULSE I SUGGEST YOU USE HIGH NUMBERS LIKE “500.0f” OR “5000.0f”
