# Tutorial: Make a parkour
|
||
|
||
In this tutorial you build a short jump-and-run course: a start platform, platforms over a deadly
|
||
pit, a ramp, stairs, a round platform, a checkpoint, a line of coins and a goal with a working
|
||
exit. It takes about 20 minutes. You should know how to move the camera (see
|
||
[Navigation](04-navigation.md)); everything else is explained on the way.
|
||
|
||
|
||
|
||
## 1. Create the level
|
||
|
||
1. **File → New level…** (**Ctrl+N**).
|
||
2. **Level name**: `My Parkour`. Keep the **Base level** (Village chapter 1 – it provides grass,
|
||
stone and wood textures, coins and checkpoint posts) and the suggested **TestLevel chapter**.
|
||
3. **Start with**: **Flat floor**. You get a 16×14 grass floor with a player start and an exit.
|
||
4. Click **Create** and **File → Save** (**Ctrl+S**) once, so the project has a file.
|
||
|
||
The flat floor will be your start area. The course will lead away from it over a pit.
|
||
|
||
## 2. Make the pit deadly
|
||
|
||
Anything the llama falls into must kill it, otherwise it lands on nothing and falls forever.
|
||
|
||
1. Press **B** for the **Brush** tool and choose **Death plane**.
|
||
2. Drag a large area next to the floor where the course will be – generously, it costs nothing.
|
||
The plane is invisible in the game; in the editor it is outlined.
|
||
|
||
Alternatively, **Geometry → Death plane height…** with **Add a death plane over the whole grid**
|
||
puts one under the whole level at once. Its height should be well below your platforms (default
|
||
−1.5).
|
||
|
||
## 3. Platforms over the pit
|
||
|
||
1. In the Brush tool choose **Platform**.
|
||
2. In the Inspector set **Top** to `stone` and **Sides** to `stone2` with the swatch buttons
|
||
(optional).
|
||
3. Drag a 2×2 footprint a little away from the floor's edge, release, move the mouse until the
|
||
top is at about 0.5 and click.
|
||
4. Draw two or three more platforms, each a bit further away and a bit higher.
|
||
|
||
Gaps of 1–2 cells are comfortable jumps; 3 cells needs a run-up. Keep height differences under
|
||
about 1 cell at first.
|
||
|
||
> **Tip:** Draw one platform, then use **Geometry → Array duplicate…** (**Ctrl+Shift+D**): 4
|
||
> copies, **Offset X** 3, **Offset Y** 0.25 makes a rising row in one step.
|
||
|
||
## 4. Ramp, stairs and a round platform
|
||
|
||
* **Ramp**: drag the footprint in the direction it should rise, release, move the mouse to the
|
||
height of the high end, click.
|
||
* **Stairs**: the same; keep **Walkable (invisible slope)** on, otherwise the llama cannot climb
|
||
them.
|
||
* **Round**: drag the diameter, then the height – a round platform. **Segments** sets how round
|
||
it is.
|
||
|
||
Select a brush and drag its orange (sides) or green (top/bottom) handles to fix its size. **[** and
|
||
**]** turn the selection by 90°, **Page Up/Down** raise or lower it.
|
||
|
||
## 5. Check the collision
|
||
|
||
Press **C** to show collision. Every surface the llama can stand on is coloured; the death
|
||
plane shows as material 30. Look for:
|
||
|
||
* platform tops without colour (collision switched off),
|
||
* small gaps between pieces that should touch – **Level → Check for problems** reports gaps under
|
||
0.2 cells.
|
||
|
||
## 6. A checkpoint
|
||
|
||
The llama should not have to start over after every fall.
|
||
|
||
1. Open the **Objects** panel (left dock) and click **Checkpoint** in **Quick setups**.
|
||
2. Click on a platform in the middle of the course.
|
||
|
||
You get a checkpoint post with its respawn point just in front of it. Falling after passing it
|
||
puts the llama back there. See [Objects](09-objects.md) for the details.
|
||
|
||
## 7. Coins
|
||
|
||
1. Click **Coin line** in **Quick setups** (or the **Coin line / arc** tool, **O**).
|
||
2. Click above the first platform, then above the last one. Coins appear every *spacing* along the
|
||
line, following the floor.
|
||
|
||
**Coin arc** places coins on a circle: click the centre, then a point on the circle – nice over a
|
||
round platform.
|
||
|
||
## 8. The goal
|
||
|
||
The template's exit is still on the flat floor. Move it to the end of the course:
|
||
|
||
1. Draw a **Block** as the goal platform at the end.
|
||
2. Click **Exit** in **Quick setups** and click the middle of the goal block's top.
|
||
|
||
That places a **LevelDoor** in the cell centre plus a 1×1 floor with collision material **16**.
|
||
The door only fires while the llama stands on material 16 in its cell. In the options bar, choose
|
||
where the exit leads (for example the next chapter of a world).
|
||
|
||
3. Select the old exit on the flat floor (the LevelDoor and its small floor) and delete it
|
||
(**Del**), so the level has one exit.
|
||
|
||
## 9. Play-test
|
||
|
||
1. **F5** (**Play**) builds the level, installs it as a mod and starts the game directly in it.
|
||
2. Run the course. Fall into the pit once to see that the death plane and the checkpoint work.
|
||
3. Press **Escape** in the game to quit straight back to the editor.
|
||
|
||
To test a hard jump without running the whole course: point the camera at the platform before
|
||
it, so the middle of the view lies on its top, and press **Shift+F5** (**Play from camera
|
||
position**). The llama starts there, facing the way the camera looks. If there is no walkable
|
||
collision at that spot, the editor tells you instead of starting.
|
||
|
||
## 10. Iterate
|
||
|
||
* Jump too long? Select the platform and nudge it with the **Move** tool (**W**) – with
|
||
snapping (**G**) on, steps are 0.25 cells by default.
|
||
* Too easy? Make platforms smaller (handles) or add an **Invisible wall** that forces a detour.
|
||
* Add decoration: a **Fence** along the start, a few **Trees**, a library piece (see
|
||
[Importing meshes and the library](07-meshes.md)).
|
||
* Run **Level → Check for problems** before you share the level, then see
|
||
[Sharing levels](17-sharing.md).
