Hi,

layer 0 is full of sprites made solid. layer 1 has sprites without that behaviour. The player can't walk along the upper sprites, because the sprites in the first layer are solid.

How to create a kind of whitelist for moving?

yes, i guess only sprites can be "blocked" with r49-. I dont see a way to make a tiled background solid, which would also make no sense at all.

U need minimum 2 layers. 1 to get a background, and 1 for solid elements and the player.

oh ok, i didn't open the system folder in the actions panel before. Thank you :)

I'd see it, but it is not available for keywords like "loopindex", which are defined before the action.

Anyway, i tried to fit the coordinates of the grid into an array, but the output doesn't work. Text keeps "0". U got any ideas?

therefore u need that parametric view of your circle:

(r*cos(t)+x0,r*sin(t)+y0)

else you need the distance/2 between A and B, the "rotation point". at the start of ellipse events, there must be

xk=r*cos(t0)+x0

yk=r*sin(t0)+y0

if this is correct u need

tan(startAngle)=sin(t0)/cos(t0)

for the following frames.

when u got this, the new point of C is

x= radius*cos(endAngle)

y= radius*sin(endAngle)

If u speak german, this might help you:

uni-protokolle.de/foren/viewt/45551,0.html

for instance:

t0=10?=Pi/18

t1=120?=2/3*Pi

(1,2)=(2*cos(t0)+x0; 2*sin(t0)+y0)

x0=1-2*cos(Pi/18 )=-0,969615506

y0=2-2*sin(Pi/18 )=1,652703645

target point:

xk=-1,969615506

yk=3,384754453

how did you make the background solid?

Is there any keyword list here on Scirra to take a look at the sense of keywords like "Loopindex" in the Event Editor?

A kind of expression / function list for c2?

Is there no way to set the array grid data without having a grid as sprites?

hen, you will have a "For each Ground" loop in which 2 actions Array.Set at XY will be used.

First one: X is Loopindex, Y is 0, Value is Ground.X

Second : X is Loopindex, Y is 1, Value is Ground.Y

And there you have it. Your array will be filled with the X and Y positions of each Ground sprite instance.

To access it : Array.At(X,Y)

If I want the position X of my 9th instance : Array.At(9,0) (9 is the 9th instance, 0 is X).

If I want the position Y of my 52th instance : Array.At(52,1)

This is the information i was searching for. Just didnt know how to access more than one value for an instance.

I will try this and post a little tut for success in time. :-)

So I should use the index of an array as pixel positions?

I'm not sure if this is the best solution.. <img src="smileys/smiley24.gif" border="0" align="middle" />

jump = shift key.

U can not change this binding with r49-.
