Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

How to create a slippery slope?


I wanted to make a sliding slope similar to the ones found in Super Mario 64. Are there existing blueprints/instructions how to make one? If not, where should is start?

Example from Mario 64: https://www.youtube.com/watch?v=R5eyPx_TFyo

Use impulse or add movement.

I used actor with simple collision box to define slide volume, and arrow component to set world space vector for slide direction.

When player enters this collision box - I send him an event that he is in sliding area with parameters: 1. boolean ShouldSlide 2. vector SlideDirection

In his Tick function ShouldSlide (true) activates simple AddMovementInput function with SlideDirection.

When player is out of collision box - I also send him event that deactivates sliding (ShouldSlide = false).

This approach works well if you disable all other input/controlls during sliding.

In case you need any controls during sliding - try to experiment.

There are few more things here, like change max speed and disable jump.
