Blender 2.5xx and IPO curves?

Game Engine Game Engine Support and Discussion

Thanks for the help so far, I am making progress and am now working on explosions and special effects, (OH NO! I hear you gasp)

I am using this tutorial here to create an explosion, it is one of the few where the demonstration blend works with Blender 2.54. The problem is that there does not appear to be a speciffic “IPO” curve button in 2.54. I have got the “scaling” onto an “F-curve” but I cant figure out how to add the “fade out”

To quote the tutorial:

Now go to the ipo editor. You should see a curve for ScaleX, ScaleY, ScaleZ. Click ColR and … Do this for ColG and ColB…
Where are these buttons in Blender 2.54?

I know they exist, ie Blender 2.54 supports them, because I can see the footprint in the tutorial blend. But for the life of me I cannot find them.

I’d be also interested in this - a way to make Color R/G/B/A to appear editable in new objects (without first creating them in 2.49).

If you want to animate anything right mouse click over its value and select add keyframe. This will then add a channel in the graph editor for that parameter. If you want to add a colour channel do this over the colour swatch in the material settings, for an objects scale while the mouse is over its scale value etc etc

You can found the RGB setting when you click on the plane and then on texture and then open colors. There you can change the color. To insert the keyframe you must rightclick and chose “insert Keyframe”. But the curve are not appears in the “F-Curve Editor”. When you now make two keyframes and replay the animation you can see that the color value change and also the preview changes.
But in the game engine it doesn’t work. So I think it’s an bug in blender 2.5x.

I also noticed that the colours were changing on replay, though the curves themselves were not appearing and am glad to here that it was not just my stupidity.

In order to quickly solve my original problem, (and allow me to advance,), I imported the “explosion object” from the demo directly into my project. I cant really edit, (or create,) the explosions, but this works and using multiple instances of the demo explosion and some delays, I can get my “ships” to “blow up” and fracture into “debris” in a very satisfying fashion.

Though it would be nice to be able to do it properly.
