GUI Virus Effect Demo You can buy this on my site if you don't want to use Unity's Asset Store. Web Site This is on the Asset Store for $5. This is a script for Unity3D that is meant for, but not limited to, computer-themed games. It shows GUI Window popups that have different effects to simulate annoying virus popups. The popups have 2 effects that can be toggled on or off at any time... 1. Run from cursor - If the cursor touches the popup window, the window will move away. 2. Shake - The window shakes all over the screen. A few others things this script is able to do... 1. Stay On Screen - A toggle-able option to keep the window from going off the screen. 2. Multiple Popups - You can have multiple popups appear on the screen. You can specify how far apart each popup appears. 3. Close Button - You can change whether the window has a close button at the top right. 4. Yes, No, Ok - Depending on the type of window you choose (Error or Warning), the buttons will be displayed. 5. Buttons with a purpose - You will be able to set what function is called when the Yes, No or Ok buttons are pressed.
