Fixed it, the bug was pasting with an effect in r160 onward. Download in first post.

Note it won't work in releases older than r160 so I also added a separate download if you're using an older c2 release.

If you calculate the signed difference of the angle of the objects every tick and add that to a variable you can get the total degrees moved around the center object.

signed angle difference of b to a = angle(0,0,cos(b-a),sin(b-a))

Example showing the total degrees moved around the center object.

Here's the formula, it's a vector projection if you wish to google more about the math behind it.

Distance traveled at anglle = (curx-oldx)*cos(angle) + (cury-oldy)*sin(angle)

Well I only program as a hobby so my fingers don't have a chance to go lame unless I break them at work. :-/

Here's the capx:

To get the events in your project open this capx and your capx in different tabs of the same instance of Construct. Then you can copy/paste the objects to your capx. The object to copy over are 3dbox, face, p, Paster and Function. After that you can copy over the events.

I found a program a while ago that can print the contents of a scrolling window. It works well for events.

I tinkered a bit with the example and got the perspective correct so the base matches the sprites. So if you're currently making the game just leave sprites for the bases of the buildings and the 3d can be added later once it's working. Once working the 3d will be on a seperate layer above the game layer and below the HUD layer. It will take a bit more tweaking to get to that point and I'll upload it when it's done. Be advised though that the polygon sorting isn't correct at times esp when boxes are near each other which is kind of distracting. I'm pretty sure it can be fixed if I sort the polys with a topographical sort which is in my todo to add to the capx.

No eta, but my weekend starts soon so I should have some time to work on it.

Cheers

Wouldn't doing a system compare of the LayoutName expression work?

No, the functions aren't exposed. The workaround is to call a function in the event sheet and set the parameters there.

Thanks for the fix.

Those recommending Paster for 3d probably were referring to this capx:

http://www.scirra.com/forum/suggestion-simple-3d-objects_topic82718_post483742.html#483742

Paster provides little to provide 3d other than an action to draw a distorted texture. The rest is math and logic.

The capx isn't simple but it could be tweaked and extended to make the game you have in mind, but as it is now it's incomplete.

I use a free account of dropbox for all my capx uploads and have no problems with it.

The problem can be thought of how to find out if a point is inside a polygon.

Here is capx with one solution:

https://www.dropbox.com/s/q8geaer8sa26f ... .capx?dl=0

Edit:

You can eliminate the need for variables if you add a imagepoint to the right-center of the line object and do this:
For each Sprite For each line | compare: line.y>sprite.y != line.ImagePointY(1)>sprite.y | sprite: x < (line.ImagePointX(1)-line.x) * (sprite.y-line.y) / (line.ImagePointY(1)-line.y) + line.x ----- + Sprite: set animation frame to 1-Sprite.AnimationFrame[/code:wl2fbtnb]

After fiddling with it a bit I don't find the custom behavior's push actions useful at all so I tried a few other methods. One that came to mind is to use the 8direction behavior instead and use events to set the horizontal and vertical velocities. It didn't work ideally since the 8direction often stops short of the walls if going too fast.

If you're fine using boxes with no rotation for the walls for now here is a capx. It uses a simplified case of the Separating Axis Theorem to do the push out and wall sliding. I was using it in another capx and found it to be a very clean way to do the wall sliding. I'll try to extend it into a plugin one of these days if I get time.
