1. Collisions; What's the way to make flag an object to collide? The Solid behavior seems turned off when combined to another behavior, like say Bullet.
You can see in my .cap, I tried a lot of different ways (bullet speed, custom movement, asin, acos...) all unsuccesul. Basically I want the little baddie that's following my character to collide and slide along walls so I can use walls to stop its course (like in Earthbound).
Unfortunately you provided the .caproj file, without providing the other files.
Either you put a zip containing the full folder, or save your project as a single .capx file for this purpose.
2. Timers; In Construct classic you could create a Wait object that you would use to count milliseconds. Now it's nowhere to be found in Construct 2 and I'm sure there is a easy way to manage delays...
3. There are no Box objects anymore? Trigger box has to be sprites? The bunch of basic sprite drawing tools also seem to have dissapeared. How do you position hotspots/pivot points now? Just wanted to know if that stuff just moved somewhere else.
Other than that I miss the Ctrl+P shortcut... but that's it. :)
My cap file;
For 2. and 3. C2 has been and is still in developpement.
Most of the plugins of CC haven't been ported yet to C2. In the future they probably will.
For now, yes you have to use sprites to "emulate" box/trigger plugins and there is no image/point/hotspot editor for C2. You have to do your images out of C2 and the hotspot is nothing but the center point of your image.
For the wait, you may workaround using the "every X sec" event combined with group. (The group is only enabled when you need it, and contain only a "every 0.1 sec" event for example, disabling the group as last action).
C2 is yet to "grow" and being build up. I guess your needs might get fulfilled in the next monthes/years of developpement.
