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 I dynamically switch one texture in a ui widget to another?

So I'm trying to create a stealth game, in which a player is chased by a monster constantly and want to give feedback to the player on if the monster can see the player, when he can't see the player this image is displayed on the HUD:

alt text

And when the player is seen I want to display this image:

alt text

I can get the idle green eye to appear when its a static material, but this doesn't allow me to change the image and leaves me with an output that looks like this:

alt text

I supect that the issue could be one of two things:

  1. That I have made the base colour parameter the wrong type of parameter

  2. I am casting the dynamic material incorrectly

This is my Material Graph: alt text

And this is the graph where I set the widget to the view port in the player character blueprint and material as dynamic: alt text

Any help in this would be very much appreciated, thanks!
