Thanks for the replies, I had issues with sticking on sheer walls (using wall jump and sort of slide, not got it right yet), but realised it was because my blocking volumes werent at 90 degrees, so sorted now.
Kittiewan I ran through that tutorial when starting, invaluable. I have as you said set up a seperat collision sprite for character, and also a seperate sprite with physics pinned for physics interactions, works great. I loved Sqiddsters game, will try and incorporate gravity shifts in, makes a uniquely fun element to the game.
For my game I have created a 3d stage, and although complicated to work out which layer pieces of the scene should go on, it looks great! Looking forward to getting gameplay elements in to show it and see what people think.
I have a question about tiling. I have put a background layer of stars (for paralax) Then 2 more layers for platforms (for 3d look). My stage is around 5000x5000 pixels. As you say this is too big to run well, and wont display in some browsers (mobile in particular). What is the best way to split into tiles? Would I just use photoshop (my mainstay app) to cut into say 1024x1024 tiles and then just line them up in Construct 2? If so what is the best way to get perfect alignment? And how will this effect how the level is displayed and accessed by resources?
