Join Steven Moser for an in-depth discussion in this video Swap fixtures, part of Building a Physics-Based Platformer in GameMaker Studio Using GML.
- [Instructor] It'll be easy for us…to swap out our physics fixtures.…All we need to do is update…our ducking and unducking script.…I'm gonna double clip the ducking script.…And when we check for the down arrow pressed event,…we first want to remove…the currently bound running fixture.…So, we'll use the function physics underscore…remove fixture.…We'll pass at the ID of the incidence…that we want to remove the fixture from.…
Which, in this case, is our player object incidence.…We have a built-in variable since we're calling it…from the actual player object.…We can just use ID.…This is the incidence ID of the player object.…Keep in mind that you can…have multiple incidences of a single object.…We only have one incidence of our player object…but that's not always the case.…ID is the way to reference that unique incidence.…For the next argument,…we pass our reference to our bound fixture.…Which we called in the create event, boundR.…So, that will remove the running fixture.…
Now, let's bind the ducking fixture.…We'll use the function physics underscore…
