I would greatly suggest applying the math found in this article. As it is, the results you're getting are somewhat unpredictable.

I'm not positive as to why you are unable to jump, but here's a suggestion anyway.

Take a look at using some Bezier Curves, or possibly DeCasteljau's Algorithm for help in generating a math-driven...

A function I have written relies heavily on trig to achieve the desired results, but using Math.atan2() takes too long to execute the script at the desired speed.

Is it possible to calculate trig...

I'm having a bit of trouble coming up with the right approach to achieve a particular effect.

I want to make a "ripple" effect using BitmapData.draw(), such that the final image can be rippled...

I'm a bit vexed by the change in speed along the curve. This should not be happening.

Didn't have time to look at the source of your formulas, but just to make sure, try googling "VB, Bezier, K.O....

Has anyone tried using the document stack to expand the maximum number of audio channels permitted by the player? Is it possible to "mix down" a multichannel document as a single channel within a...

I'm not certain, but I think what you may want to do is use a BitmapData approach to this. If you don't refresh the BitmapData surface, it will retain the previous frame. If you experiment with the...

IP: again you've lost me. Maybe a picture would help explain?

Back to code...

IP: I'm a little bit confused as to exactly what you're asking. Do you mean a blending of contour to create more of a "blob" pattern, or do you mean some sort of blending of colors that is different...

One thing I wanted to incorporate into my engine was simulated light sources. I managed to come up with a fairly versatile solution that can achieve some fairly decent results even though it's...

Are you actually loading the entire massive sheet of tiles and then extracting what you need from it?

If that's the case, why not load each tile seperately and construct your own tile sheet using...

I'm not in the same league as most of the guys on this thread, but I'll add my perspective anyway.

I prefer to work things out mathematically, so the first step for me is to build a flexible and...

Sorry Trog, either the file's been removed or Player 9 won't run it. Nonetheless, I want to begin working with ColorMatrixFilter to see what it can do. It sounds powerful.

For the time being, I'm...

I have nothing against per-pixel calculations and heavy use of BitmapData, I wish more could be done without sacrificing framerate on lower-end machines. But if you want to simplify your engine so...

In the process of figuring out my game engine, I've decided to create an open discussion about the methods I've found to achieve certain visual effects so that others can learn from my experiments...

First of all, I don't know what sort of nesting structure you're using for your movieclips. The structure you should be using is something like this:

World.Hero.Animations[]

If this is what...

One thing I am uncertain about is whether or not you want the speed of your character to be affected by the distance travelled. For instance, your character might walk at a mild pace if it's a short...

What you're trying to do sounds rather easy, you just need to do a few things to make it all come together. Here's just one possibility:

Scale down a duplicate of your travelling bitmap when it is...

When a snapshot of an mc is taken using the draw() method, is the entire mc captured, then cropped to the specified dimensions of the BitmapData in question, or does it only capture the region...

Tiling would not work well for this scenario because it would require alot of resources to achieve a much more inefficient variety of the same desired result.

The fix I came up with was to use a...

I just refactored the class to accept BitmapData.draw() and it looks like a pretty good fix. The only issue I'm having with it now is slowdown. There's a noticable lag when I zoom out too far, but...

I've run into one of those problems that might not be resolvable, but I'm giving it a shot here to see if anyone has some ideas on what to do.

Objective:
I want to construct my 2D game levels by...

First off, it's embarrassing to even post this considering how simple it is to code, but it just isn't working and I don't know why.

The goal: uniformly change the scale of a rectangle relative to...

I just went to alot of trouble to write a custom class to do what I need, but now I'm uncertain if it would be the best way.

Here's an extremely brief outline of what I built:
A custom class that...

I am developing an engine for my game and a large majority of the way things are drawn to the screen is directly dependent upon the ability to set the fill color of parts of the sprite...
