360 Degrees shooting problem!

[izac]

Hi! i've made a simple 360 Degreese object that can move useing Cos() and sin(). But why arn't the bullets? here look at this code:

+Repeat while SpaceBar?
--Create active2(800,600)

+Active2 Flag(0) is off?
--Active2 position = (active1X,Active1Y)
--Active2 valueA = active1 ValueA
--Set active2 flag0 on

+Always
--Set active2X = (Active2X + cos(Active2(ValueA)) * 5
--Set active2Y = (Active2Y + sin(active2(ValueA)) * 5

But the bullets look like 32Dir. And i can't seem to fix it!

P.S:ValueA is the Angle!

Any help would be great thanks!

My guess is because you are dealing with integers instead of floating point numbers. Store in a alterable value the floating point position that it should be, and in any calculation use 5.0 instead of 5 (or whatever) to make it use decimals. Then make it set the position to the alterable value, and never read the actual position because it is too imprecise.

:S could you show me a piece of code?

I do not understand what you mean.

First check the angle calculation is working by having a counter showing the angle and ensure it is not limited to a small range of values for some reason.

Second the line is missing a closing backet (or has an extra open):
Set active2X = (Active2X + cos(Active2(ValueA)) * 5

I imagine you should have:
Set active2X = Active2X + cos(Active2(ValueA)) * 5

thanks for your help! i've figured it out!

I used value B+C for xVel and yVel. And it works!
