Oh, and there's also the background collision mask on those runtimes that support it. That should be very fast as all it's doing is reading 2-bits of data (although you do need to calculate the...

By "grid-based", I don't mean that the actual movement has to be grid-based - only that the map is grid-based. That way, a two-dimensional array can easily be used to label a grid space as either...

Yes, fine collision checks are slow. On the other hand, bounding box collision detection should not be computationally expensive at all, so try disabling fine collision detection in the object...

What you're talking about is "collision avoidance" (that's the proper term to google), as opposed to true pathfinding.
Dex's method seems like it should work.

Alternatively, I remember seeing an...

It won't be what you want to hear, but the simple solution is to just not use the built-in image editor. Honestly, it's complete junk compared to any number of other free image editors (GIMP,...

The action to start the ForEach loop is under: Active (Coin) -> Count -> For each object
...which is not an obvious place to look for it, I agree!

The matching condition for the second event is...

You have to wrap the collision event in a ForEach loop.

+ Always
-> Coin: Start ForEach loop

+ Coin: On ForEach loop
+ Coin: Overlapping Player
-> Add 1 to Score
-> Coin: Destroy

The diameter of circle1 is always going to be equal to the smaller of the screen width and the screen height (depends on whether its landscape or portrait).

The diameter of circle2 is always going...

Use a string tokenizing / parsing extension - there are quite a few to choose from - and set the delimiter to newline$ (or you can copy & paste a newline character from notepad).
Alternatively, you...

There's no need to use two ForEach loops there, although it wouldn't actually hurt if you did. If you do that, you're essentially just bypassing the built-in object pairing / scope system altogether....

It's actually not too complicated, but it's not documented at all in the help file, which isn't great...

I made a few little examples here:...

You've already got the formula there - you just need to strip out the max(), min() and turnRate() parts.

D = ((( ATan2( ship.y - YMouse, XMouse - ship.x ) - ship.angle + 540 ) mod 360 ) - 180 )
...

I just modified my previous example to use an array instead of a list (might be faster?), and took out all the graphics that aren't mine.

Yes, I've had something like this working before for multiple targets, but only in a squad level turn-based strategy game, so performance was never a serious concern.
After a little experimentation,...

Not sure about why enemy movement goes wrong above a certain speed, but I'd guess it relates to your "MoveTimer" variable.

Having said that, I can see how the pathfinding engine as a whole could...

The hard way, I'm afraid - load it as a text file, and parse it yourself :(
You could also just make up your own syntax that's easier to parse - delimited strings are pretty simple...

I think scripted events can be seen as an extension of normal NPC conversations (which you will find discussed elsewhere).

Personally, I'd use XML or something similar.
Here's a quick example:

I would usually do something like this:

You should always think of the built in X and Y position values as being "write only" - always use alterable values to store an object's position coordinates as floats, and never retrieve an object's...

I don't think I have that particular example any more, but I also don't think it would be of much use to anyone either, as it wasn't a general purpose array editor - it was really just suited to...

Surely they shouldn't be picking random paths though? They should be going somewhere with a purpose.

eg. In a rollercoaster tycoon game:
If they're hungry (haven't eaten in a while), they should...

I feel like it should be do-able using a shader - something along the lines of:

return tex2D(img, float2(In.x - (fPixelWidth*xOffset), In.y - (fPixelHeight*yOffset)));

The challenge is to...

The built-in editor is fine for what it is - there's no point in trying to reinvent the wheel, when there are so many great third party image editors out there (including free ones).

You could have inserted delimiters in the string, and then a tokenizing extension would have made it marginally easier.
Otherwise, use a fastloop to loop through the string in pairs.

A flashlight (aka "shadowcasting") effect is actually very tricky to pull off - especially with multiple light sources (which is also likely to make it slow)....

Yeah, that would work - sounds like a very good idea actually.

The original version of my example didn't use actives - it just used a list of strings (to allow for a much more flexible level...

See the first event.

I get the feeling this is going to be one of those that's very specific to the *exact* thing you're trying to achieve, and there will almost certainly be some piece of information you haven't...

Are you using "paste into background" or "add as backdrop"?

"Auto tile" is the term you're looking for - google that and you'll find countless explanations.
There's at least one example on the clickstore, or my own here:...

Look into Brashmonkey Spriter - that's the closest you're going to get.

I've certainly never tried it, but I see no reason why you couldn't (although it's definitely not more flexible).
The potential issues that immediately spring to mind are:

It wouldn't affect performance, but DO NOT do it.
You should create actives to use as containers for all the values that are used in the same part of your program.
For example, create an active...

You've pretty much answered your own question. If you get 300+fps with just the shadows, but that drops to 30fps in game, then obviously the problem is not with the shadows - it's some other part of...
