A_ZoomFactor is weird

[lemonTasteIceTea]

since you can't do something like A_ZoomFactor(zoom-0.1) i made an acs script which when called gets the current zoom factor, subtracts it by 0.1 and gives the new factor over to my decorate script
well instead of the camera zooming out, it zooms in
this is the code

Code: Select all

#library "bzoom"
#include "zcommon.acs"

int zoomf = 1.0;

script "bzoom" (void) {
	zoomf = zoomf - 0.1;
	SetResultValue(zoomf);
	if (GetCVar("tgc_debugging_fun")== true) {
	Log(s:"Zoom factor is now ", f:zoomf, s:".");
	Delay(35);
	zoomf = 1.0;
	Log(s:"Zoom factor is 1 again.");
	}
}

i have no clue if it's from decorate's fault or acs' fault
i've seen from the log that the first zoom factor is 0.900003
might be something from that
also i need it the script to zoom out more and more because one specific weapon i am making can either shoot one shell or 10
do you guys have any idea why this is the case?

that's probably because of fixed point, you can't return fixed point from ACS in zandronum. what you can is to return integer properly aligned and multiply it in decorate.

ACS: SetResultValue(100 - 10); // 90

DECORATE: A_ZoomFactor(0.01 * CallACS("myzoom")) // 0.01 * 90 = 0.9
