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"

Help with the logic: Graffiti System

Hi there !, im trying to make a graffiti system, and i have a question about decals.

First, here's what i made (https://www.youtube.com/watch?v=3rHaWIrS8E8). The decal spawn with alpha 0%. My question is, Can i "shoot" in specific area and set the decal to alpha 100% (in an area where i shoot) ? And if i use this (if it possible?) how can i checke the graffiti is completed ?. Someone throw this idea, if i make a virtual grid maybe this can checke if the graffiti is 80% completed or 100%.

*Here's an example :https://youtu.be/PN5kZTu5ae4?t=4m17s*

Or this is more simple, let me know please. Thanks

Hey Naks312!

Not tested but maybe try adding some sort of collision bounds when you start painting so you can have some sort of ratio to work with. Then, using the point you've painted on, start adding decals that are masked with a paint shape and at the vector parameter's position on the UV's. Then have the texture of the graffiti, and used Screen Aligned UV's to make them match up seamlessly.

Hope this helps!
