how do i get an actor to follow the mouse in rotation, as in a turret following the mouse to aim? cos im stumped

[jimmynewguy]

if you mean rotating to face the mouse then use

Code: Select all

angle=direction(x,y,xmouse,ymouse)/nframes;

But for some reason xmouse and ymouse always tend to be off so your better off making an actor called mouse and on create actor setting it to follow mouse then change the turrent code to

Code: Select all

angle=direction(x,y,mouse.x,mouse.y)/nframes;

EDIT: Put this in draw actor

xmouse and ymouse are screen coordinates. So to use them, use

Code: Select all

direction(xscreen, yscreen, xmouse, ymouse);

In you're example, you're adjusting angle. angle is for movement, and requires directional_velocity.
If you want to adjust the animation use

Code: Select all

double dir = direction(xscreen, yscreen, xmouse, ymouse);
animpos = (int)((dir + 5) * .1) % 36;

This is for a 36 frame rotation animation (for other values you'll need to adjust the numbers.

when i type fast i do weird things, i meant angle to be animpos...but your code is better

[savvy]

ok, its still not working. heres the actual thing

[jimmynewguy]

the animtion of your turrent rotating should start at zero degrees (facing right) and rotate counterclockwise in order for the code to work

o, ok

[savvy]

ok, now with that done i need to know how to make a bullet travel in the direction of the mouse.
(ive never done rotation code Bfore)

[savvy]
