scripting language support for event handling About Truespace Archives These pages are a copy of the official truespace forums prior to their removal somewhere around 2011. They are retained here for archive purposes only. scripting language support for event handling // Feature suggestions 1  |   Order by default Post by Lee // Jun 30, 2007, 3:48pm Lee Total Posts: 13 Might event based programming with scripting language support - something/anything with asynchronous event callbacks be possible with Truespace in future? Real life is full of asynchronous events. JScript/VBScript do not appear to support asynchronous events. Its hard to work around this using polling in a scalable way without both: bogging down the CPU and upping the complexity on the developer. For example: Scriptable objects that act as a web service end-points could open up TS to interfacing with a lot more languages in an independant way, but - this I think requires asynchronous event support. Games within truespace/player might run smoothly without lockups and jerkyness etc if they did not use polling.

It can be used together with other items to execute a control brick on demand rather than in the usual continuously clocked manner. I agree that event handling is a very powerful feature. Sounds like you have more in mind than responding to simple keypresses. Post by Lee // Jul 2, 2007, 7:39am Lee Total Posts: 13 Interesting: Havn't seen an example using the WatchDog obj. yet. I believe it 'polls' a single input and outputs when it changes. Polling in general probably slow scripts down though. I see TS also has a 'selection change event' obj that control outputs upon obj selection - as used in the interactive replace tool activity. So there might be a few more event objs spread around.
