[COMPLETED 075A] Sin, cos, tan

[Juutis]

It would be really useful to be able to use the trigonometrical functions (or whatever they are called) sin, cos, and tan in scripting. At least I didn't find any way to use them, so I guess they're not there.

[AndyCR]

that's a very good point.

(bookmarks this page for RF2)

In the new RFwithPhysics release will be a Math command (added by Nout toghether with all the new features) that will allow all the
math functions. You will have to wait some week.

[Jay]

It would also be good to have the reverse functions asin(), acos() and atan() which return radians from a given number.

[federico]

RFwithPhysics never officially came out so these kin of commands weren't implemented in the current source.
If QoD wants to add them here's the command (you will probably have to change some variable's name):

Code: Select all

	case 119: //value = Math(Function, Value1);
			  //value = Math(Function, Value1,Value2);
		{
			strcpy(string1, arguments[0].str());
			if (!stricmp(string1,"abs"))
			{
				PARMCHECK(2);
				returnValue = (int)(abs(arguments[1].intValue()));
			}
			else if (!stricmp(string1,"fabs"))
			{
				PARMCHECK(2);
				returnValue = (float)(fabs(arguments[1].floatValue()));

			else

				sprintf(szBug,"Math function %s does not exist!",string1);
				CCD->Engine()->ReportError(szBug, true);
				exit(0);
			}
			return true;
		}

The code is by Nout naturally.

ah that's good thanks!

[Jay]

got it implemented into my version of the source. I will make it available soon so that everyone can use it.
