- Index
The game file to import and load for this session is 5961_03_07.stencyl.
We need to open up the Collision Groups window in the Stencyl Settings dialog box:
- Click the Settings icon on the main Stencyl toolbar.
- Look down the list of icons that are shown in the left panel of the Game Settings dialog box and click on Groups.
- In the Collision Groups window that is now being displayed, click on Tiles under the GROUPS heading at the top of the right-hand panel.
We have displayed the current collision settings for the Tiles group as shown in the following screenshot:
The Collides With section in the previous screenshot, which has been highlighted with an oval shape, shows which other collision groups have been configured to collide with the Tiles collision group. Currently, both the Players and the Actors collision groups are configured to collide with the Tiles group (remember, the Tiles group is the one we selected in the right-hand panel). Note that the Players button and the Actors button are shaded darker than the Tiles button, which shows us that they are currently selected.
This means that any actor that is placed in the Players group or the Actors group will react to a collision with a tile. Note that, if we configure a group such as Tiles to collide with Players, then the Players group will automatically be updated to reflect this change!
