throwing a sprite at a target help needed

Rook Zimbabwe · Post by **Rook Zimbabwe** » Fri Jul 11, 2008 11:46 pm

OK so far I have been assisted with taking out a target in PB. But now I am stuck on another matter.

Starting at 0,0 I want to throw a sprite at a target where I mouseclick.

CODE EDITED... But it still won't go towards a target... just a diagonal line!

Code: Select all

Two versions of code are below

Will be more and more a 'Missile Command' style:

OK 99% fixed... still got to make the projectile and target dissappear when intersect...

You getting a lot of inaccuracy on the targetting still.
I have done a little bit to address this, but atm am out of time, so I will do some more if I find time when I get back home .- (tonight hopefully.) ( Changing from direct bullet, mouse sprite points to a couple of different (non displayed ) sprites for collision testing )

Baldrick · Post by **Baldrick** » Mon Jul 14, 2008 4:28 am

Found time to have a bit of a play here..
I have used the IceSoft example code used above here.
For the bullets I have created a 2nd non displayed bullet of 1 x 1 pixel size which uses the projectile x,y coordinates for collisions testing.
For the sight collisions I have made a 2nd non displayed sprite with a size allowing the displayed bullets to appear to be entering the sighting cursor. I have disabled the displayed bullet zooming as this bit needs more work to get accuracy.
As I don't have a copy of your real cursor I have just created 1 in the form of a little scope sight...
Still not 100% accurate, but getting closer. ( there is a couple of points around the screen where the bullets will pass by the cursor still )

Baldrick,
GREAT SOLUTION! use a point as a checker! I would have thought of that myself... in about 2,000,000 1/2 years [ plus 16 days!] )

I have disabled the displayed bullet zooming as this bit needs more work to get accuracy.

I think the problem with the scalaing is the rotation... I think the rotation throws everything else off! I am going to try your code with simple scalaing and no rotation as well to see whats up!

Thanks for the brainwork!
