Problems with A_OverlayOffset

[Ershantik]

I'm trying to make an overlay that starts offscreen and then slowly moves in from the left.

Code: Select all

EFCT A 1 A_OverlayOffset(LEFTLAYER, -73, 0)
EFCT A 35 A_OverlayOffset(LEFTLAYER, 73, 0, WOF_ADD)

The sprite is being interpolated, but the problem is that it's happening too fast. It's moving into position almost immediately instead of over 35 tics, and nothing I do is changing it. How can I slow down the offset so that it's spread out over every tic of the frame?

You will have to move the overlay over many frames instead, interpolation only happens between single tics:
EFCT AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA 1 A_OverlayOffset(LEFTLAYER, 2.085, 0, WOF_ADD)

Thanks, that works. Still, that seems very inconvenient for moving sprites over long distances.

You need to understand the differency in definition.

EFCT A 35 means "show sprite efcta for 35 tics".
While
EFCT AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA 1 means "show 35 different franes of efcta for 1 tick each".
Pretty different, don't you think?

Fair enough. Either way, I ended up reducing the number of frames and increasing the offset to make it move faster, so it's not too bad now. Thanks for the advice.
