Here How I detect match

I think I need to share a simple approach to detect match on screen, since I'm working on match-3 puzzle.

Really simple but to make it work we need to modify collision polygon shape as showed up below:

Say Your sprite size is 64 pixel, So You need to reduce polygon size by 2 from each edge or equal 60 pixel.You get the idea each adjacent sprite will have a gap 4 pixel between collision shape.

If you have a look at my blog http://myconstruct2dev.blogspot.co.uk/2 ... tch-3.html there is an open source match 3 game. The code in the event file "matches" should work for a "match on screen" approach (e.g. you don't have an array or tilemap or string which describes your grid of colours to match), though it is all functions.

rexrainbow has a few plugins that might be of use:

Neither of the first 2 posts are asking for how to do a match - they are showing how to do it without having to load half a dozen non-standard plugins.

Thanks gumshoe2029 I knew rex has alot of usefull plugins. I prefer to build the system from scratch to understand what is under the hood.

This is always a good method. Especially if you have the time to do it.

Now it is more rich with 4 & 5 combo items!
