Wanted to post it in case it's helpful for someone. </p> <p>This type of functionality is useful for all sorts of things. Maybe you just want one character to look at another or a gun barrel to follow the cursor etc.</p> https://www.lexaloffle.com/bbs/?tid=35358 https://www.lexaloffle.com/bbs/?tid=35358 Sun, 15 Sep 2019 14:45:33 UTC Alpha Masking in Pico-8 <p>Hi all,</p> <p>I was wondering if anyone might know how to make an alpha mask like you might do in After Effects. A good example that I've been trying to replicate with no success is the classic Star Wars transition where you have a circle that gradually gets smaller, until the screen is black. </p> <p>I know that I can draw a black rectangle and a circle, then scale the circle down but I cant figure out how to cut the circle from the rectangle to create the mask. </p> <p>I hope I'm making sense.. it would basically be a black rectangle with a scalable transparent circle in the middle that cuts through the black revealing whatever is drawn onto the screen below it.</p> <p>Any help would be much appreciated. Thanks!!</p> https://www.lexaloffle.com/bbs/?tid=35310 https://www.lexaloffle.com/bbs/?tid=35310 Tue, 10 Sep 2019 13:55:36 UTC Help with collisions on scrolling map <p>So I'm new to Pico-8 and really enjoying it so far. I'm trying to get tile collisions working on a scrolling background but just can't seem to figure it out. Here's what I have so far. Any help would be appreciated. Thanks!!</p> <p> <table><tr><td> <a href="/bbs/?pid=64955#p"> <img src="/bbs/thumbs/pico8_yyubogugu-0.png" style="height:256px"></a> </td><td width=10></td><td valign=top> <a href="/bbs/?pid=64955#p"> yyubogugu</a><br><br> by <a href="/bbs/?uid=37818"> phaselock.studio</a> <br><br><br> <a href="/bbs/?pid=64955#p"> [Click to Play]</a> </td></tr></table> </p> https://www.lexaloffle.com/bbs/?tid=34425 https://www.lexaloffle.com/bbs/?tid=34425 Sun, 02 Jun 2019 18:03:50 UTC
