i'm also a C2 (& programming) newbie so the deltatime might be redundant, but i'm pretty sure it's needed so that the sprite moves at 'speed' pixels per second instead of per frame.

hi alisa, here's a simple way of moving a sprite around with waypoints:

https://dl.dropbox.com/u/52354372/waypoints.capx

very basic, no acceleration or turning & the collisions are innacurate, but should be what you're after for simple background anims.

hi, here's how i've been doing my drag-drop with overlap checking:

https://dl.dropbox.com/u/52354372/drag_drop_overlap_test.capx

you could also do a simple check for the dragdrop behavior where you store the sprite's position on drag start, then on drop if it's overlapping another object you move back to that stored position.

but i would go with a movement tester sprite like in the example - most games with drag-drop do something similar, & it just feels more intuitive having the preview of where you're moving.

note - i've used a family in my example file for containing all blockable objects, so it might not open in the free version of C2.

As for how to start & organize your project, just play around with the platform behavior & the 'simulate control' action for your auto running at first. Do some experimenting & see what's fun.

Yep it was a picking problem. Fixed it (learning a lot in the process) & thought i'd post the results so other Construct2 newcomers can have a look:

Thanks for the ideas, i'll check them out.

So, another question about something that I've got half-working...

Any idea where I'm going wrong?

here's a test file with some coloured beams & a target sprite which changes colour based on adding beam rgb...

dl.dropbox.com/u/52354372/rgb_beams_test_1.capx

works nicely, but since i'm new to construct i thought i'd post this & ask if there's a simpler method that i'm missing.

nice idea & it works in more situations than before, but still not right...

Thanks for taking a look. This is similar to where I'm at at the moment- it works for single overlaps but breaks with multiple ones:

I think I might just stick with the simple conduction...

Another question - here's the setup so far, using ramones first example:

<img src="http://i.imgur.com/98T5L.jpg" border="0" />

Now say that the conducting sprites have a 'resistance', & their frame number increases along the connected chain like so:

<img src="http://i.imgur.com/0LsZ1.jpg" border="0" />

Could a family picking method like the one used above do this?

I've tried making the (what I'm assuming to be a) triggered loop on event #4 into one that iterates the anim frame as it steps through each sprite. That doesn't work & I'm probably wrong about it looping - it might just be picking all connected family members at once...

Thanks! This is very helpful in learning Construct's subtleties.

Families are the elegant solution (I'm tempted to shell out the 80 quid just to play with them), & the 2nd hidden sprite example is very clever. Since it appears at the end of a chain, provided there's no branching, it could serve some extra visual effect.
