Advanced draw help...(for collision etc.)

[speckford123]

Can you collide with things drawn into a canvas?
if so, how?
Also how can I erase parts without erasing the whole?

I never use the draw functions so I have no idea....

A way you can erase part of the canvas, is, lets say you press E for erase. In the keydown event press e, go to the script editor and type in:

Code: Select all

setpen(255,255,255,0,3);
draw = 0;

This way when you press E, the color of the pen will be white (which basically is what erase is)
To change it back, lets say again that you press R for red or something, go to the keydown event and press r, then go to script editor and type in:

Code: Select all

setpen(255,0,0,0,3);
draw = 0;

This way, the color of the pen is set back to red. If you want, you can adjust the 3 in setpen(255,0,0,0,3);
draw = 0;
to change the line thickness. Hope this helps. Btw, I dont think that you can make a collision with the canvas drawing, but then again, Im not sure.
I also atatched a demo if you need it.

um, there's only a ge file without data and everythin'...
'course this can't work...

error, can't load this'n'that...

cud u please fix'at ?

[Freddy]

Ugh. Thats annoying, I thought that there wasnt any data. Anyway, here is an exe. version. It wont help much , but it will substitute until I can figure it out .

[speckford123]

Well I wanted the canvas erased transparent, oh well.

[Kalladdolf]

another question, how do u erase parts of a normal actor (like in Worms, when a grenade explodes, it erases a part of the ground) ?

[Freddy]

What do you mean?

[DilloDude]

You cannot just erase part of a normal actor, unless you already have animations set up to do it. However, if you draw it on a canvas(such as using draw_from or loading it yourself) you can erase parts of it. It gets a little tricky if you want to cut fancy shapes, but it works.

[Freddy]

Hey Dillodude! Nice to see you back on the forums!

[Kalladdolf]

Freddy, I know what's wrong with your GE file!
you used text, right?
FONTS ALSO BELONG TO THE GAME DATA!

[Freddy]

Ooooohhh! Thats why it wasnt working! But how would I get the text data?

[Kalladdolf]

nothing
just upload your ged file and the data folder.
(if you create a ged file and save it, GE creates a data folder automatically in the same folder as the ged file)

[Freddy]

Yay! I figured it out! Ok, here it is. EDIT: I downloaded it, and I found that the .exe version is in there to, but once you open the data folder, you can go to the .ged

[Freddy]

Oh no! I was wrong about the erase technique. There is a way that the erase can be transparent, when you choose the setpen action, there is a place for transparency, set it to 1. You can set the color to whatever you want, it doesnt matter what the color is (because it is transparent).

thanks for the help, but without collision stuf like destructable terrain(like worms) is still far away, oh well on to other things
