This spot light lets you choose a projector map via an extra menu. By default it display the leadwerks logo.

 

The material file contains this line:

texture0="abstract::projectormap.dds"

A simple Spotlight that projects a projection-map.

 

Usage:

1. Place files with the other light (not neccesary.)
2. Use your own dds file for the projector-map.dss.
3. Drag a projector spotlight on screen.

i put a watch on this topic, just in case you come back

this 'projection light' isn't really nessecary any more since the point light supports a material file which can display the dds file you want.

Thank you, i had no idea how to do this.

following your suggestion i found an example in the wiki

TEntity light  = CreatePointLight(15,0);
MoveEntity   (light,  Vec3(0,5,0) );
SetShadowSoftness(light,2);
SetShadowmapSize(light,512);

TMaterial lightMaterial = CreateMaterial();
SetMaterialTexture(lightMaterial, LoadTexture("abstract::flashlight.dds"));
PaintEntity(light,lightMaterial);

i'll try it this evening

You don't have to make any script at all since the spotlight that comes with Leadwerks can do this for you already.

Just drag a spotlight in the scene en go to its properties. There you can choose a material file. Use an image that you want like bars of a window for example.

 

However if you still want to make it via your own scripts, just let me know. I''ll gladly help you out.

Thank you Aggor, it's a relief to know you'r arround to provide help when we need it.

 

I have another related question. Maybe there is a way to specify the spotlight should only cast light on specified entities ?

 

if not, then i'm not sure how to do it. perhaps, disabling all entities and lights i don't want, do a renderlight with only the spotlight and wanted entities, then re-enable everything and let framework render the world ?

[AggrorJorn]

That is a tough one. I have no idea how to do that. It requires a little more knowledge about rendering lights inside the LE core.

Hi Aggror,

i tryed with the editor, but when i set my selector mat file nothing happens, my selector.dds is not projected.

and if i go back to the light properties later the material property is not kept and empty again.

 

here's my material and dds selector.zip

 

and a screenshot

The Spot light script that comes with LE does not inherently paint the light with the material selected. The material selected is applied to the default gmf model. So just add a new property to allow you to do this, like in this example:
